alsa died after 2.6.12.2 kernel upgrade

DeusExLinux · 07-13-2005, 03:22 PM

I was running a custom 2.6.9 kernel, and everything was working fine.

I decided to be adventerous and upgrade to the 2.6.12.2 kernel (I grabbed the vanilla source from kernel.org). I compiled fine, got my madwifi to work fine, and then tried to play a song.

it decided that it wasn't going to work.

I have checked the volume settings (alsamixer, and the mixer I use) and nothing is muted, everything is turned up. the volume is turned up on my laptop. The modules are loaded. No sound.

The sound card in my laptop is the intel8x0, and the module is loaded at boot through hotplug, I blacklisted the intel8x0m module, as it is suppsoed to mess with the intel8x0.

It acts as if it is playing, but no sound coming out.

I decided to boot back into my old kernel, 2.6.9, and when I did, the sound decided it didn't want to work in there either!!!! I don't know what happened here, as I didn't do anything to alsa. The config file I used to config my new kernel is the same as the old kernel. Is there an error in alsa in the new kernel version? Or did something magically happen to screw up my sound server?

this is uber-frustrating.

Any help would be much appreciated.

Ih ave a hankering that something might be using the audio device, but I don't have any stray processess running that have sound, and there's no real reason that anything SHOULD be using the sound, but when i try to modprobe -r snd_intel8x0 I get a "module is in use" error.

the alsa module is extremely sensitive to new kernels, you should reinstall/rebuild the module

as you didnt list your base system i cant offer a way to reinstall

You could always compile the alsa libraries from source. That's the only method that proved successful for me when I upgraded kernels.

Goto www.alsa-project.org and fetch these source packages
1. alsadriver
2. alsa lib
3. alsa util
4. alsa tools

then do the usual ./configure, make, make install procedure to install them.
I'm not sure if you need to recompile all four of them or not, but it worked for me
