My sound went away :(

I’m running OpenSUSE 11.1 32-bit. I don’t listen to music or watch video every day that I’m in Linux, so what I think happened was a recent update killed my sound. It was working about a month ago. But now, nothing. It’s not muted, and it works fine in Windows. Is there a known fix?

Kernel updates can cause this problem. (It has happened to me on occasion). Have a read of this ALSA update how to. It explains how to add a temporary multimedia repository, which you use to update alsa via zypper, then remove when done. Post back if you have problems. :slight_smile:

It tried that, and when I restarted and picked the new entry in the GRUB menu, OpenSUSE 11.1 - (pae), it would not start the X server. Tried logging in and then startx, but it would not load and it gave me an error. I had to Ctrl+z and restart. Here is the error:

When I choose the default instead of the pae from the GRUB menu, I do get my X server, but I still get no sound.

This will happen, because the nvidia module is compiled against a particular kernel version. (If you want to change kernel, you will need to install matching video driver, but for now I would avoid introducing more problems).

Now back to the audio problem. After updating alsa drivers, you may need to configure sound with YaST > Hardware > Sound again. After this the sound system should restart if all is well.

If you still have problems, post output of

rpm -qa |grep alsa

uname -r

so we can see where your at.

I would also work through this troubleshooting guide. Read carefully, and be methodical in your diagnostics.

The fix was only temporary and would not survive a restart. Step 2 in your link did work, until I restarted the computer to make sure the fix was permanent. YAST tells me my audio controller is not configured, after the restart.

The outputs as you requested:

randybob@actionfrank:~> rpm -qa |grep alsa
randybob@actionfrank:~> uname -r

You have 2 alsa drivers:


I would delete the unstable one (as root) with

rpm -e --nodeps alsa-driver-unstable-kmp-pae

Done, but I still have the same problem.

It is more likely that the recent update to pulse audio has caused your problem. Check the sound icon (bottom right corner of the screen) and see if the sound is shown as muted.

If so then it will be pulse audio the problem. The easiest way to correct this is to go into yast - software and uninstall all the bits with pulse (except libpulse - which should be left). Then re-start your p/c and see if the sound is back to normal.

No, it’s not muted. That was one of the first things I checked.

Nevertheless, pulse can cause problems for some users (if installed), as mentioned here:

Worth looking into.
