CentOS 7 with SB Audigy FX - No Sound


Good Day All,

I am running CentOS 7 on an IBM x3550 m2 with an SB Audigy FX PCIe card that uses the Realtek ALC898 chipset. The system "sees" the card as does the ALSA tools, etc.; however, there is no sound.

I have been researching this for weeks to no avail. I noticed that there are no definitions within any ".conf" file in the /usr/share/alsa/cards directory to support the ALC898 chipset.

I am considering the purchase of an ASUS Xonar DX card that has the AV100 chipset which is defined in the CMI8788.conf file. Has anyone had luck with this card?

Any advice would be certainly appreciated!

Regards,
Russell

Hi Russell...

Welcome to the forum

Not sure I can help here but out of curiosity, please post the results of the following commands...

Code:
lspci -nnk | grep -i -A7 audio
Code:
lsmod | grep snd
Code:
aplay -l
Please also include the section concerning your sound card (if any) using this command...

Code:
dmesg
You could try this command to make it easier but I'm not sure if it will work...

Code:
dmesg | grep -iC 3 "snd"
Last but not least, what does alsamixer show? Please include a thumbnail of that, if you could. Thanks!

Regards...

Hello again Ardvark71,

Here is the audio-card information you originally requested.

I hope this helps you and hopefully, my "sound" issue can be resolved.

As you can see below, the OS "sees" the audio card; but, I do not hear anything through the speakers or headphones.

At the very end of this post is the text output on the terminal from the "aplay" and the "play" commands.

Once again, thank you so much for replying to my original post and thank you in advance for looking at this post!

Regards,
Russell

Hi Russell...

Thank you for your reports and for going above and beyond, however, I'm not good at reading ASCII. Would you upload a screenshot (or image) of what you see from this command...

Code:
alsamixer
Also, for the "dmesg" command, you could also try...

Code:
dmesg | grep -iC 3 "snd_hda_intel"
Thanks!

Actually, amixer produces full output. Please use code tags when pasting.

Hi Emerson and Ardvark71,

Thanks again!

I am working on the screenshots (using "gimp" create screenshot). They create an image file with a ".xcf" extension.
There are 3 screenshots--can I upload those directly or should I "zip" them and upload the zip file?

Also, I'm not sure what you mean by using "code tags when pasting" and by "system - no", "pulseaudo - no".

Please advise.

The dmesg | grep -iC 3 "snd_hda_intel" command produced no output.

Thank you again Ardvark71 and Emerson!
This means a lot to me and I really appreciate your time and effort in trying to help me!

Best regards,
Russell

Hi Russell...

I'm sorry, in terms of uploading them directly using the "Attach Files" feature, none of those options will work. These are the only file formats accepted: gif jpeg jpg log pdf png txt. You should be able to use the "printscreen" (or "Prt Sc") button on your keyboard to create a screenshot. You might need to use one or two other keys in conjunction, such as "Ctrl." There also might be another program that you can use to do this mentioned in post #2 here. Another option would be to create an account at a free image hosting site, such as flickr or imgup, if you don't already have one and then upload the screenshots there and post a link to the shots. You would just need to make sure the file format you want to use, such as .xcf, is supported on the site.

When you create or reply to a post in advanced mode, directly above the text window you write in, you will see a button that looks like this: #

You will then something close to this: [ CODE ] [ /CODE ]

Put the results of the commands between those two.

Hi...

Yes, that was a thought I had, too. It's easier for me to see the actual image in this case, hence my suggestion of "alsamixer."

With alsamixer you can be never sure all mixers are on the screen, if there is more than fits the screen one needs to scroll right with arrow key, a still image won't be good any more. You need a video for that.

Smile CentOS 7 with SB Audigy FX - No Sound

Hello and Good Day Ardvark71 and Emerson!

Here is more output and my attached screenshots that I converted to "jpg" files.

This is so confusing to me. The system "sees" the card and the chipset: Card: HDA Creative, Chip: Realtek ALC898
Note: when testing, I moved the sliders up for headphones, etc. -- still, no sound.

amixer output
Code:
[pika@yeti ~]$ amixer
Simple mixer control 'Master',0
  Capabilities: pvolume pswitch pswitch-joined
  Playback channels: Front Left - Front Right - Rear Left - Rear Right - Front Center - Woofer

  Mono:
  Front Left: Playback 16462 [25%] [on]
  Front Right: Playback 16462 [25%] [on]
  Rear Left: Playback 16462 [25%] [on]
  Rear Right: Playback 16462 [25%] [on]
  Front Center: Playback 16943 [26%] [on]
  Woofer: Playback 16943 [26%] [on]

  Limits: Capture 0 - 65536
  Front Left: Capture 22379 [34%] [on]
  Front Right: Capture 22379 [34%] [on]
Here is something I read about; but, have not rebooted to test:
So, if you think there is any value to this approach, I can reboot and test again.
If not, I will comment out the "options" line.
Code:
[pika@yeti ~]$ cat /etc/modprobe.d/snd-hda-intel.conf
options snd-hda-intel model=auto
#options snd-hda-intel model=acer-aspire
Again, thank you so very much for everything!

All the best,
Russell

p.s. I'm starting to get the hang of how to post things properly. Thanks for your patience and grace! This is an awesome site!

Hi Russell...

You're welcome! Assuming there is nothing I missed from your reports, which looked ok to me...

After a bit of research, it appears there are issues with your card and few others in that line. There has been a patch released but, from what I understand, you will need to recompile your kernel to include the patch. That I can't help you with, that's a bit beyond my knowledge and ability.

However, if you want to give it ago, please see these threads for more information and the patch...

I can't guarantee it will resolve the issue but if you know how to do this kind of work, it might be worth a shot.

However, if not and/or the potential loss of your current copy of CentOS is not feasible, then you might want to give the ASUS Xonar DX (that you mentioned in your first post) or another card a try.

Hope this helps. Let us know how it goes.

Regards...

Smile CentOS 7 with SB Audigy FX - No Sound

Hi Ardvark71 and Good Day to you and Emerson!

I certainly appreciate everything that you and Emerson have done in trying to help me out!

In your last response, you mentioned that maybe I should give the ASUS Xonar DX or another card a try.
That's just what I was thinking of doing--rather than rebuilding the kernel--and here's what I discovered:

The Xonar DX uses the AV100 (CMedia Oxygen HD chipset) that is defined in the "aliases.conf" and the "CMI8788.conf" files under the /usr/share/alsa/cards subdirectory.
Note: My current SB Audigy card with the ALC898 chipset is not defined in any of the "conf" files as shown below by "grep"--this may be the problem.

Link to the ALSA Vendor Matrix for ASSUS: http://www.alsa-project.org/main/ind...ix:Vendor-Asus <--- verified that the Xonar DX is supported by ALSA
Code:
[pika@yeti cards]$ pwd
/usr/share/alsa/cards

[pika@yeti cards]$ grep -i AV100 *.conf
aliases.conf:AV100 cards.CMI8788  <----<<< this seems promising :)

[pika@yeti cards]$ grep -i CMI8788 *.conf 
aliases.conf:AV66 cards.CMI8788
aliases.conf:AV100 cards.CMI8788
aliases.conf:AV200 cards.CMI8788
aliases.conf:CMI8786 cards.CMI8788
aliases.conf:CMI8787 cards.CMI8788
CMI8788.conf:# Configuration for the CMI8788 chip
CMI8788.conf:CMI8788.pcm.front.0 {
CMI8788.conf:CMI8788.pcm.default {
CMI8788.conf:CMI8788.pcm.surround40.0 {
CMI8788.conf:CMI8788.pcm.surround51.0 {
CMI8788.conf:CMI8788.pcm.surround71.0 {
CMI8788.conf:CMI8788.pcm.iec958.0 {

[pika@yeti cards]$ grep -i ALC898 *.conf
<no output>
The ASUS Xonar DX needs Auxiliary Power
Please see the attached "Auxiliary Power for PCIe" and the "ASUS Xonar DX PCIe Sound Card" images.
Code:
The system is an IBM x3550 m2 that has an 8-pin molex connector on the system board to support an optional video card.
I have worked out a series of cable connections that would begin with an 8-pin molex connector ending with a 4-pin floppy disk connector.
I just have to verify that the voltage the on-board 8-pin molex connector provides is the correct voltage required by the Xonar DX.
Please let me know if this approach seems logical.

I have been trying to find a card that is known to work with CentOS 7.x that would be plug-and-play.

If you know of such a sound card, a low-profile PCIe card, especially one that *does not* require auxiliary power, please let me know

With much appreciation and best regards,
Russell
p.s. God Bless you and Emerson!
