No sound on Asus M2Ne sli mainboard w/openSUSE-11.2

I have a problem with my sound card so if you can help me I will be very happy!
The sound card is cm-6501 incorporated on a asus m2n-e sli mainboard

/usr/sbin/ =

rpm -qa ‘alsa

opensuse:~ # rpm -qa ‘pulse

opensuse:~ # rpm -q libasound2

opensuse:~ # uname -a
Linux opensuse #1 SMP PREEMPT 2010-03-16 21:25:39 +0100 x86_64 x86_64 x86_64 GNU/Linux

opensuse:~ # cat /etc/modprobe.d/50-sound.conf

options snd slots=snd-usb-audio

gLM6.VsPijs0Hbo8:PnP Audio Device

alias snd-card-0 snd-usb-audio

And if it is not challenging for you, in yast-hardware I have no sound/audio shortcut :smiley:

Thank you a lot

IMO It would be best if you started a new thread

Post moved to new thread of its own.

This post has been moved from applications to hardware, as it was inappropriately tagged on to another thread in the applications section. Both web based and NNTP users are welcome to post here now.

Moved to new thread.

I looked for the Asus M2Ne motherboard on the Linux incompatibility list: Motherboards

I note it is reported as not compatible with some older Linux versions: ASUS M2N-E SLI (KERNEL < 2.6.20)

I do not know if it is compatible with kernels after 2.6.21

You may wish to check your motherboard BIOS settings to see if sound is switched ON in the motherboard.

You could also try updating to 1.0.23 of alsa: Alsa-update - openSUSE Note after you think you have finished your alsa update, check :

rpm -qa '*alsa*'
rpm -q libasound2

and if you have the same versions as before, then your update failed and you need to try again.

You could also write a bug report on openSUSE component “sound” on openSUSE-11.2.

Attach (don’t copy and paste, but attach) to the bug report the text file from running:

/usr/sbin/ --no-upload

and that will create the file /tmp/alsa-info.txt which can be added as an attachment. That has bunch of technical info that may show the alsa dev what is wrong with the alsa driver, IF you also describe the audio symptoms.

Note the SuSE-GmbH packager for sound is also an alsa developer, and if he fixes this, the fix gets sent upstream and ALL Linux distributions will benefit from your efforts with him.

There is guidance here for raising bug reports: Submitting Bug Reports - openSUSE … The alsa developer/openSUSE packager, may ask that you try a few different alsa versions, and hence if your schedule is too busy for such support (and I definitely know what that can be like) then its probably best NOT to write such a bug report.

Don’t reference this thread, as the SuSE-GmbH packager refuses to read forum threads. Its important the bug report has all the salient information.

Good luck !!

ty for helping and sorry for posting (originally) in a bad location

My soundcard works, I’ve updated Alsa according to my kernel BUT it still stereo, not 5.1 and I don’t have yast-hardware-sound shortcut. It is still missing

After your alsa update, can you provide again the information you provided in your first post ? ie again output URL given when running:


and output of

rpm -qa '*alsa*'
rpm -q libasound2

rpm -qa ‘alsa


rpm -q libasound2

btw, and no yast-hardware-sound shortcut there. in yast I have no “sound”, “audio” search string

Do you remember I asked you after updating to SPECIFICIALLY CHECK your alsa version numbers after updating to ensure they were updated ? Did you do that? I note some were NOT updated (see the red above). ie specially:

  • alsa-tools-1.0.23-9.3.x86_64.rpm
  • alsa-tools-gui-1.0.23-9.3.x86_64.rpm
  • alsa-plugins-pulse-1.0.23-28.1.x86_64.rpm
  • alsa-plugins-pulse-32bit-1.0.23-28.1.x86_64.rpm
  • alsa-firmware-1.0.23-8.1.noarch.rpm

Was there a specific reason why you elected not to update those? … I’m trying to understand so I can understand better your approach/method wrt trying to get things working.

I have never heard of “Performous-plugin-alsa” . Please, what is that for ?

It looks to me that you are ONLY getting sound out of some plugin USB device and NOT out of the motherboard.

My new configuration is:
/usr/sbin/ =

opensuse:~ # rpm -qa ‘alsa

opensuse:~ # rpm -q libasound2

  1. I used “Alsa-update - openSUSE” link and I updated only the selected software from that picture because I thought that only those must be updated.
  2. “Performous-plugin-alsa” perhaps is a trash left from my previouses tries to install the sound-card. I’ve seen that is installed but I didn’t delete because I didn’t know if is a required package or not.
  3. in windows, my sound card is seen as a usb device because it “eats” usb resources. A strange thing is that if I have the sound started (in windows) the usb composite device (from device manager) shows that I have an usb connected that “eats” like 60% of the usb resources. If I start the webcam ALONE for a video-conferince it eats too like 50-60%. If there is an audio-video conferince so, the sum of them are > 100% and the computer locks and sound will never be usable till reboot. So, the motherboard’s (m2n-e sli) sound card (c-media 6501) eats usb resources

Sorry for not executing right the #1 and #2 steps

The sound card works, but it is stereo (not 5.1) and when I start X, when it plays the welcome sound i get this message
"The audio playback device PnP Audio Device (USB Audio) does not work. Falling back to PulseAudio"
… any suggestions? :open_mouth:

From that script, its pretty clear:
Simple mixer control ‘Speaker’,0
Capabilities: pvolume pswitch pswitch-joined penum
Playback channels: Front Left - Front Right - Rear Left - Rear Right - Front Center - Woofer - Side Left - Side Right
Limits: Playback 0 - 197
Front Left: Playback 35 [18%] -30.37dB] [on]
Front Right: Playback 35 [18%] -30.37dB] [on]
Rear Left: Playback 0 [0%] -36.93dB] [on]
Rear Right: Playback 0 [0%] -36.93dB] [on]
Front Center: Playback 0 [0%] -36.93dB] [on]
Woofer: Playback 0 [0%] -36.93dB] [on]
Side Left: Playback 0 [0%] -36.93dB] [on]
Side Right: Playback 0 [0%] -36.93dB] [on]
You have all the 5.1 speakers muted at 0%. Muted means no sound. That ‘may’ be relevant. Why NOT use your mixer to move the volume up ?

I don’t know much about 5.1 surround sound, but I documented my experience here: Exploring surround sound in Linux - openSUSE Forums

I wrote that guide, and I confess to being a bit frustrated, because most of the time I simply can not get users to install alsa completely. Note I wrote in the guide:*

and then select for update all of your PC’s alsa applications, including “libasound2”. Do not add new alsa applications, just update your existing ones. See the example on the left.

*ie … update “all of PC’s alsa apps”, … and an ‘example’ is just an ‘example’, … its not hard fast instructions because everyone has different alsa apps installed.

How do I fix this guide so that the sort of approach you made is not repeated?

Sometimes I feel like just deleting the update alsa article because it fails far too often … anyway …thats my frustrations :\ and we are here to solve your problem (and not mine). :stuck_out_tongue:

Thats a bug in KDE and likely not relevant nor harmful.

I provided instructions above on raising a bug report.

I updated the section in the guide to try and better describe what need be done (to update ALL alsa apps that are already installed):
SDB:Alsa-update - openSUSE
… others have also struggled with my previous guidance in the guide, so hopefully this update I made now will help.

ok. the mixer volume is not muted…

I will try to see if I can manage to make it work.
Your tutorial is good but I made a few mistakes following it… :smiley:
Thank you for your time.

I’m always looking for suggestions on how to improve my wording in the alsa-update wiki. Sometimes I get too familiar with the method to update, and its hard to sit back and put myself in the shoes of someone who has never seen this before. Hence hiccups such as you encountered are very instructive for me. If I appear grumpy at times when others encounter hiccpus, that is MY own personality weakness that I need to find a solution for ! :slight_smile:

Don’t forget the ‘raise a bug report’ approach. I know it reads to be painful, but if you succeed in getting the openSUSE sound packager’s attention, then they are one of a 1/2 dozen people in all of Linux who know the Linux sound driver really really well.
