Upgrades

Q: What does the letter at the end of OPAMP model mean such as OPA627AU, OPA627BU, OPA627BM, OPA627SM?
A: The first letter, ‘A’,’B’,’S’ means ‘OPAMP Grade’ and the quality is better in following order.
 ‘A’ < ‘B’ < ‘S’
The second letter, ‘U’,’M’,’P’ means ‘package type’.
P: DIP type
U: SMD(SOIC-8) type
M: Metal Can type(It protects against the noise and electricity)
Therefore the SM type is the highest price as the best sound quality.

Q: What extension boards are available for Auzen soundcards?
A: Our Extension board for X-Meridian has been released. If you connect the Extension board onto the X-Meridian and future supported sound cards (such as the X-Fi Prelude), you will be able to get a signals through all ports simultaneously.

We had planned manufacture the X-10 extension board for X-Plosion and X-Mystique. Unfortunately, we could not release the Digital I/O module/bracket because C-Media's CMI8768+/CMI8770 audio chipset could not support the external SPDIF Input to Dolby Digital Live or DTS Interactive encoding.

Q : What was the upgrade X-Meridian upgrade program?
A :We launched an upgrade program for X-Mystique and X-Plosion sound card owners just prior to the X-Meridian release. The program has now ended. The price, terms and conditions are still available in the press release.

Q : The box mentions "Swappable dual DIP type OPAMP controlled preamp circuits." How does that benefit me?
A : The Operational Amplifier (OPAMP) upgrade is for anyone who wants the best possible sound from the analog outputs of the X-Mystique or X-Plosion sound card. Using the OPAMP chips we suggest*, the analog signal becomes stronger and clearer, recordings have greater detail and accuracy, and expansion and separation is improved in the soundstage. If you use the Toslink S/PDIF optical connector* to transfer the audio bit stream to your home theater system, this upgrade does not apply to you.
* See related FAQs on this page.

Q: I want to upgrade the Operational Amplifier (OPAMP) chips. What do you recommend?
A :We highly recommend the Texas Instruments / Burr Brown OPA2134PA. You will need four OPAMPS to upgrade the X-Meridian, or six OPAMPS to upgrade your X-Mystique or X-Plosion card. You can change the OPAMP for the Front channel on the X-Fi Prelude. These OPAMPs are readily available from DigiKey.com. To install the new OPAMPS...

1. Power down your PC completely, ground yourself by touching the metal casing of the computer, and avoid placing the circuit board on an ungrounded surface.
2. Take note of the direction of the existing OPAMPs. On the X-Meridian they all face the same direction. On the X-Plosion and X-Mystique the top two face one way, the bottom four face another.
3. Use a common chip puller (available at Radio Shack®) to remove the old OPAMPs.
4. Carefully insert the replacement OPAMPs facing the same direction as the old ones. Reinstall the card and restart the PC.

Q : Where can I find the Digital I/O module/bracket for the X-Mystique and the X-Plosion sound cards?
A : We are sorry to report that Auzentech will not release the Digital I/O module/bracket because C-Media's CMI8768+/CMI8770 audio chipset could not support the external SPDIF Input to Dolby Digital Live or DTS Interactive encoding. However, onboard optical input (with external SPDIF Input to Dolby Digital Live or DTS Interactive encoding) are supported in the Auzentech X-Meridian which uses the C-Media"s CMI 8788 chipset.

Connections

Q : What is S/PDIF?
A :S/PDIF stands for 'Sony/Philips Digital Interface'. It's a protocol that is used to transfer digital signals without quality loss between two digital devices such as DAT-, MD- or DCC-recorders and also soundcards. Originally it was invented to support 20bit resolution at fixed samplerates like 32, 44.1 or 48kHz. Most consumer soundcards are transfering only 16bit data while pro audio cards now often support 24bit resolution. To transfer the signal, either an electrical/coaxial cable with one RCA connector for stereo or an optical cable (usually Toslink) is used.

Q : What connectors are you using for optical connections?
A :All our soundcards with optical S/PDIF interface use Toslink connectors. These connectors (invented by Toshiba ... that explains the name) are also called 'square connectors' in some situations.

Q : What are the maximum cable lengths for digital connections?
A :Optical Toslink connections with high quality cables can be relativly long - up to about 30m there are no real problems. It is not easy to get cables with that length however. For coaxial connections, it is important to use high quality 75ohm cables. They can be relativly long then as well. If you want to use normal audiocables for digital connections, you should be careful with the length - depending on the quality, cables with more than 1m could already cause trouble.

Q : Can different type of cables change the signal quality (digital transfers)?
A :No. If the connection works (and you get a fine audible signal), the quality is always the same. If you use a cable that can't be used for digital signals, you will get loud noise or no signal at all.

Q : What is AC-3? I heard that AC-3 is transfered via S/PDIF but how can multiple audio channels be transfered when S/PDIF only supports two?
A : AC-3 is an encoded signal (also known as"'Dolby Digital" and "5.1") that is created with special ultra high end equipment (usually in professional audio/video/TV studios) and then saved in digital data files - for example on a DVD. The encoded signal can be transfered via S/PDIF but it is not a normal audio signal. This means that a special AC-3 decoder (often built-in in HiFi amplifiers) is needed to playback the separate channels. Software DVD players can also decode AC-3 streams on a PC.

Q : I have a 5.1 receiver with DTS and Dolby® Digital decoding. Can you tell me how to configure Battlefield 2 for the best surround sound?
A : Yes. Set the EAX feature to "OFF." Set the Audio renderer to "Hardware." Enjoy.

Q : Are Auzentech sound cards the best choice for playing games on my PC? With an SPDIF or Coaxial optical cable connection to my AV receiver, will I be able to hear 5.1 channel surround sound?
A :The X-Plosion and X-Meridian are good choices as they supports Dolby® Digital Live DTS in real time. The package includes an optical cable. The X-Fi Prelude is another great choice, specifically designed both for gaming and to provide audiophile-quality listening for music and movies.

Q : I have connected my old soundcard to my receiver through three analog cables, but there is no sound to my subwoofer. With an Auzentech sound card, will I be able to use a digital cable to connect my soundcard to my receiver and hear 5.1 channels?
A : If your old soundcard does not support real-time encoding, it will only support PCM 2 channel digital output. In contrast, the Auzentech X-Mystique and X-Plosion soundcards support real-time encoding and will output at minimum 5.1 channels to your Audio Visual (AV) receiver. Both sound cards include an optical cable.


Q: Can we get analog and digital output simultaneously?
A: When you set the 'Dolby Digital Live 5.1' and 'DTS Interactive5.1', it is impossible to get the Digital output with Analog output simultaneously. However, if you choose PCM mode such as Digital Audio 44.1kHz/48kHz/96kHz/192kHz, you can get 2ch PCM Digital output with Analog output on other speaker at the same time. If you own the X-Meridian, you can also select 4ch, 6ch, 8ch PCM Digital output with Analog output.



Q: :Why is there is no Analog sound with Front R/L speakers on my CMI-based Auzen soundcard?
A:See the CMI-Based Soundcard Connections page.


Q: Why is there no sound from the Microphone (or Line In) on my CMI-based Auzen soundcard?
A:See the CMI-Based Soundcard Connections page.

Troubleshooting

[ General | Vista-specific ]

Q : I have problems with noise, clicks and pops with an optical digitial connection. What can I do?
A : Usually this can be caused by a cable that is not properly plugged into the Toslink connector. Please check the connection and make sure the tip of the optical cable is clean. If this does not help, please exchange the cable to a different type / brand.

Q : After installing the sound card and connecting it to my surround sound system using S/PDIF output, keyboard and Control Panel adjustments to Volume and Balance either do not work or have minimal affect. Is that normal?
A : With Digital Audio output, output levels are controlled by the wave volume settings. Multimedia keyboards and remote controls only adjust the master volume. The third-party application "Volume Tracker" corrects the situation by linking wave volume and master volume. Volume Tracker is compatible with Windows 2000, XP and Windows Media Center.

Q : How do I get digital output when using Line In? If I want to use the Line In to listen to an MP3 player, I have to hook up a pair of headphones or speakers to the analog output.
A :If you want Line In to digital output, you must turn on the Stereo Mix–Magic Voice. You reach this setting by first launching the 3D Audio Control Panel, either from the System Tray or your computer's Control Panel.

Q : I am able to get 5-channel sound, but no subwoofer, from my AV Receiver. What setting should I change?
A : On your receiver, set your speakers to Small, not Large.
Credit: Tip submitted by Richard E.

Q: When I use the Line In or SPDIF In port, there's no sound with any speakers.
A:Only the X-Meridian supports SPDIF In. check the SPDIF In or Line In by going to Control panel >> Sounds and Audio Devices >> Volume >> advanced >> options >> properties >> Recording. Also you can select the X-Meridian in all selections at Audio tab and Voice tab.
Refer to the manual for X-Meridian the page from 48 to 49. In case of X-Plosion/X-Mystique, when you use the Line In port, you need to select Stereo mode or Direct xch mode in your receiver.


Q: How can I use my two speaker system in my PC?
A: Using two sound cards in one PC: It is possible to use both cards in one system if they are different models. However, if they are the same model, it is impossible to get any sound this way. Using one sound card with two speaker systems - If you want to use two speaker systems, you can connect one of the systems into optical/coaxial port and the other one using analog output. Then, when selecting the PCM mode, you can get both analog and digital sounds with both of your speaker systems.


Q: When I install my sound card in my PCI slot, my computer boots up, but the monitor shows no display.
A: Your PC seems to be having difficulty recognizing your sound card. Try to remove and reinstall the driver while keeping the following suggestions in mind.
-Remove the sound card, then try cleaning the PCI connector with pencil eraser (do not leave a fingerprint).
- Download the latest driver at our website.
-Try using a different PCI slot.
- Your PC may find the new Device automatically.
- Ignore the Hardware Wizard.  Double Click the setup file in the driver folder.


Q: :Why is there is no Analog sound with Front R/L speakers on my CMI-based Auzen soundcard?

A:See the CMI-Based Soundcard Connections page.

[ General | Vista-specific ]

Q: Are Vista drivers available?
A:Yes. See the Compatibility section for updates.


Q: There are some noise and distortion when I play the game. How can I fix it? [BF2, WOW, Oblivion, etc] 
A: We are aware that issues occur with a few games. The X-Meridian is more focused on the music/movie audio sources than the game audio sources or recording. Programs such as games that require high quality graphics can impact sound card performance. We are continuing to update our soundcard drivers and will post updates on our website as they become available. Updating your graphics driver, BIOS and motherboard chipset may also help reduce these problems. The following third-party link has helped some users to update graphic cards for MOD driver: [ Graphic driver update (MOD) ]

Q: My PC system freezes or has BSOD problems.
A:These can be classfied as compatibility problems or crashes with data-intensive devices. When you put use a "data-heavy" device such as webcam, WiFi card or TV Tuner card, it is possible to have a crash.Try the following suggestions:

• Update your motherboard chipset and BIOS.
• Move your sound card to another PCI slot.
  
• Run your 'Disk defragmenter software (Go to Start->All programs->Accessories->System tools->Disk defragmenter)
• Check for device IRQ number conflicts. ( Go to ‘my computer’ right click -> properties -> hardware -> device manager -> view -> resources by connection -> interrupt request IRQ ).If you think that some devices are unnecessary, right click and select disable.
• Try removing "data-heavy" devices and then testing your sound card. Set the onboard sound device to Disabled at the BIOS setup. The MIDI port and Game port need to be set as Disabled as well.
  

Q: The Dolby or DTS sounds does not come out through all channels. How can I fix it?
A: You can see the question mark Icon at the main tab in Audio Configuration. You need to select correctly according to the file type.
- When you play the MP3, WMA, AAC, CD, VCD file, set the SystemInput as 2ch and test your sounds.
- DVD with Dolby Digital or DTS,WMA-Pro : 4ch
- DVD with Dolby Digital EX or DTS ES : 6ch
- 3D Games : 8ch
Disable the onboard audio in the "Device Manager." You may also need to disable it in the motherboard bios.


Q: Is it possible to get the DD or DTS audio sources through SPDIF In? 
A: You can get the DD or DTS audio sources through SPDIF Input port when you select 'Loopback' only (because your audio source is DD or DTS Non-PCM source). If the data is PCM audio such as 2ch analog sounds, you can choose the Dolby Digital Live or DTS Interactive. The "Loopback" setting is a "passthrough" -- the non-PCM sounds simply output through your speaker directly without further processing. To make the changes, right click the speaker Icon at the system tray, select Recording Devices, Right Click the SPDIF In, go to Properties >> Custom tab, and check the box for "Monitoring."

Q: How can I play 5.1 channel digital surround sound through Optical/Coaxial port in Windows Vista on X-Meridian, X-Plosion, or X-Mystique?
A: See the CMI-Based Soundcard Connections page.

Compatibility


Q: How can I get the sound through SPDIF Input with my external device (xBox 360)?
A: The SPDIF Input port accepts stereo and PCM sound only. If the sound from the external device is LPCM format, the sound does not come out properly.

Q : Are Auzentech Soundcards compatible with Microsoft Windows Vista?

Q : Are Auzentech Soundcards compatible with Linux?
A : The C-Media-based Auzentech soundcards (X-Mystique, X-Plosion, and X-Meridian) have limited compatibility with Linux through C-Media's Linux driver for 8768/8770 and 8788 chipsets. However, the driver does not support Dolby Digital Live and DTS Interactive. According to C-Media, Dolby and DTS do not intend to open their source for Linux OS. You can download the Linux Driver for CMI8768/8770 and 8788 from the Alsa Project:
» Download C-Media Linux Drivers
As for the Auzen X-Fi Prelude 7.1, we are in discussions with Creative Labs regarding a Linux driver. We project that it will be available at the end of 2008, since our major focus is on the HDMI product line and DDL / DTS driver at this time.



Q: Does your product supports Bit-Perfect & ASIO?
A:The role of ASIO[Audio Streaming Input Output] is just Input and Output signals. In case of realtime siganls, a little latency occurs and ASIO can reduce the 'signal latency' to some degree.

• The bit-perfect output means ‘no bit errors’  output.
• Kmixer resampling causes negative effects such as latency and poor quality of sounds and the Kernel Streaming and ASIO can solve such a problems.
• The driver for our X-Meridian supports ASIO2 and your system can avoid the Kmixer resampling and the siganl comes out as bit-perfect. Even though we don’t have our own ASIO driver for X-Plosion/X-Mystique, you will have no problem using it if you use ASIO4ALL. You can download it in the link below. However, the driver does not support "bit perfect" signals.
  http://www.asio4all.com/
• "Bit-matching" is available on the Auzen X-Fi Prelude 7.1 in Audio Creation Mode only. You can select the sample rate with 44.1, 48, 88.2,or 96 kHz in AC mode (but the sample rate is fixed at 48 kHz when Dolby Digital Live is active). Bit-matching is not available in other modes (there is a fixed sample rate of 48 kHz in Game mode and 96 kHz in Entertainment mode).

Q: I purchased an Auzentech / HDA product through Bluegears. Where should I go for support or upgrades?
A: All support for Auzentech and HDA products are provided through this site, Auzentech.com. The easiest way to contact us is through the online support ticket system.


Q : What is the relationship between Bluegears and Auzentech?
A : At this time there is no relationship between Bluegears and Auzentech. Bluegears is a trademark of Bluegears, Inc, an early distributor for Auzentech sound cards when Auzentech was still known by its previous name, "HDA." Auzentech has since taken over its own distribution. If you need support for an Auzentech / HDA product purchased through Bluegears, the place start is the Auzentech online support ticket system.


Q : What is the relationship between HDA and Auzentech?
A : HDA was the old name for Auzentech. When Auzentech took over its own distribution it adopted the name Auzentech throughout all arms of the company, both in the US and Korea.


Q : Who developed X-Mystique?
A : X-Mystique was developed by Auzentech when it was still named HDA. Auzentech is the developer of the X-Mystique, X-Plosion, and X-Meridian.

X-Meridian
This section is dedicated to Auzentech's new sound card custom-designed to make the most of the CMI-8688 chipset.


Q : What is the relationship between the X-Meridian and sneak-previewed X-Purity?
A : In response to our earlier sound card sneak-preview (the X-Purity), Auzentech received feedback from the audiophile community that resulted in important changes to our next-generation sound card based on the C-Media 8788 chipset. Along with a redesign, the card received a new name, X-Meridian.

Q : Why did you select the name X-Meridian?
A : The name X-Meridian reflects our belief that this sound card marks the dividing line between all past and future soundcards, even more so than our X-Plosion sound card.

Q : How is the X-Meridian design different than other sound cards based on the C-Media 8788 chipset?
A : To the best of our knowledge, every other sound card announced to date that is based on the C-Media 8788 chipset uses the generic "reference" board design provided by C-Media. In our opinion, they are all the same sound card. For the average listener that design is good enough. Auzentech's sound cards are not engineered for the average listener, but for the most demanding audiophiles on the planet. The X-Meridian is custom-designed around the 8788 chipset to make the most of its capabilities while providing the features that audiophiles crave.

For details on our engineering philosophy, see the Auzentech Difference.

Q : How have you improved the X-Meridian design based on customer input?
A : Here are two examples out of many: We added combo Coaxial and Optical Input and Output. We created an external board for 6.35mm microphone input and Digital I/O. We knew that these and many of the other changes would not affect every customer—but their inclusion would help the X-Meridian to become the sound card of choice for the most demanding listeners.

Q : Is there an upgrade path to the X-Meridian?
A :Yes there is. Please see the upgrade section of this page.

Q : What are the full specifications for the X-Meridian?
A : The specifications are available on the X-Meridian page, and the sound card comparison chart.

Q: How can I play 5.1 channel digital surround sound through Optical/Coaxial port in Windows Vista?
A: See the CMI-Based Soundcard Connections page.

X-Fi Prelude
This section answers questions about the X-Fi Prelude, an Auzentech-designed and manufactured soundcard custom-engineered around the Creative X-Fi chipset.

Q: Why is DTS only available in Vista?
A:On the X-Fi Prelude, DTS is only available for the Microsoft Vista Operating System. The decision is related to costs and OS market share. LIke many of our customers, we are not completely comfortable with this decision and we continue to explore whether we can offer DTS for XP sometime at a later date.


Q: I need information about the Creative Media Toolbox Trial Software.
A:Please refer to the Creative Media Toolbox FAQ page.


Q: How do I get digital sound through the SPDIF port in Windows Vista?
A: In Windows Vista, the default device needs to be set according to the mode.

1. Right click the speaker icon > Playback device.
2. Set "Speakers" as the default device for Analog mode and Dolby Digital Live mode
3. Set "SPDIF Out" as the default device for Digital sound without DDL feature.

Q: What is "Error Code 37"? Is there something wrong with the X-Fi Prelude driver?
A: We apologize for the inconvenience. The problem is caused by a timeout in the underlying X-Fi chipset drivers. It is sometimes called a "Time bomb bug." The simplest fix is to download the new driver from the Updates page and follow the install instructions. We would like to extend our apologies to our customers inconvenienced by this issue. We value your ongoing participation in our mission to provide amazing PC audio solutions.

A: Disable the onboard audio device (in CMOS menu) and update the motherboard chipset driver. Also try inserting the sound card into another slot to for a secure IRQ resource.


Q: Why is there no sound from some channels?
A: Check the connections and cable. Then refer to user’s manual for connection information. Make sure that the channel configuration is correct.


Q: Why doesn't the pass-thru function work when playing a movie through digital output (S/PDIF)?
A: In your player software, select the function "Using S/PDIF output" or "Using a decoder" and set the sampling rate to 48 kHz in configuration menu.


Q: Why am I unable to use the ASIO function?
A: You can use ASIO only in Audio Creation mode. Change the mode to Audio Creation before using ASIO.


Q: Why is there no sound recorded through my microphone?
A: Select MIC as recording device on the mixer and adjust the recording level. You can amplify input gain by 20 dB with the boost option.


Q: Why is the sound on each channel not accurate when watching movies in 5.1 channel?
A: You should set the output channel to 5.1 channel or 3/2+LFE in the configuration menu of your multimedia player.


Q: Why is there too much surround or 3D-effect when playing music?
A: EAX effect can cause this problem. Deselect the check box "Using EAX effect" on the console. Or adjust the amount of effect to reduce the 3D effect.


Q: Why do I only hear music on the front speakers when I activate the CMSS-3D function to listen to music with 5.1 channel?
A: Activate the function, CMSS-3D and check "Stereo Extend." Then set the stereo envelopment fader to center. Stereo Envelopment helps you set up the listener’s position.


Q: Why does the volume seem irregular and the audio noisy when listening to music and watching movies?
A: When MP3 or multimedia files are made, audio volume are often set overly high. You may need to adjust the master/wave volume and use the SVM function to normalize the volume.


Q: Why are volume and settings values different on each console mode?
A:Game, Entertainment, and Audio Creation modes have a independent settings to optimize their functions.


Q: When I play music, why does it come out from all channels (5.1 or 7.1 speakers)?
A: Check whether the CMSS-3D function is activated. If so, deselect the CMSS-3D check box on the console.


Q: How do I change the OPAMP?
A: You can change the OPAMP for the Front channel. Pull out the existing OPAMP and insert the OPAMP you want to use into the socket. Please check the direction before inserting to avoid product breakage (match the hollow side of socket and OPAMP).


Q: How can I get advanced audio effects in Vista for my older games?
A:Advanced audio effects on Vista for older video games is made possible through ALchemy. The follow-up questions below tell how to get it, and to learn what it is.

How do I get ALchemy?
A n older version of Creative ALchemy already works with the X-Fi Prelude. You dan download it from the soundcard driver updates page (even though ALchemy is not technicaly a driver). Support for more recent versions of Creative ALchemy is coming via software updates. For a time estimate, see the X-Fi Prelude soundcard page.

What is ALchemy?
Alchemy is an ongoing project that supports only a limited, but growing, number of PC games. It is necessary because prior to Windows Vista, the Hardware Abstraction Layer (HAL) enabled DirectSound and DirectSound3D technologies to play advanced audio effects. Many games have used these technologies for dynamic audio, but those same games sound flat when played in Vista. For newer releases, OpenAL has become the favorite technology. But what about the old games? That's where ALchemy comes in: ALchemy translates the legacy DirectSound calls into OpenAL, and then passes control over to your soundcard driver. The result is full hardware accelerated 3D Audio and EAX support, just as the developers intended. Even in Windows Vista.


Q: Why do I hear cracking and popping in the audio?
A: Apparently this problem can affect a portion of users using soundcards based on the X-Fi chipset in computers that include NVIDIA hardware. Below is a quote from NVIDIA:

Creative and NVIDIA have been investigating reports of performance issues in some systems that have NVIDIA components as well as Creative's Sound Blaster X-Fi soundcard installed. There were complex, bandwidth-related issues involving memory allocation that made isolation of the issue and subsequent resolution time consuming and difficult. After thorough QA and testing, NVIDIA released a BIOS update for motherboards designed by NVIDIA and based on the NVIDIA nForce 680i SLI MCP, which has resolved such issues. For any X-Fi owners using these motherboards but are still experiencing issues, we advise you to contact your motherboard manufacturer regarding the availability of an updated bios.

 
Q: Does the Auzen X-Fi Prelude support Front Panel Audio Connection?

Q: What can I do with the Authorization Key?
A: You can use the Authorization Key to activate the soundcard's Dolby Digital Live (DDL) component.

Q: How do I get my Authorization Key for protected DDL?
A: Your Authorization Key is available for free from the Auzentech website. Visit the Online Support Desk, click the "Register" icon, and supply the requested information. Select the soundcards you own, and input the serial number. If the serial number is accepted, your authorization key will automatically appear the next tme you log into your account.

Q: I cannot find my serial number. Now what?
A: Please refer to the Serial Number FAQ.

Q: Will I need a new Authorization Key with each driver installation?
A: Each authorized user of the soundcard is allocated one key. Each key enables the user to activate the DDL software the first time, and subsequently with each software upgrade on the same PC.The key may only be used for a new installation a limited number of times.

Q: Is the DDL Authorization required for other soundcard features?
A: No. During driver installation you will be prompted whether to activate the protected Dolby Digital Live (DDL) component now or later. If you select "later," the installation will proceed but you will be unable to use DDL until you activate it. However, all other features of the soundcard driver will be available..

Q: What are the requirements for the Authorization Key?
A: Activation of protected Dolby Digital Live (DDL) requires your computer to be connected to the Internet. After you enter the key in a dialogue box, it will be validated by Creative's backend server. If the Authorization Key is valid and has not been used too many times, the DDL component will be "unlocked.".
