Reinstalling ALSA after OSS4, Debian 6.0
 

I changed out ALSA in favour of OSS4. Due to some compatibility issues with an external soundcard, I have to switch back to ALSA. However, after removing OSS4 (using apt-get purge) and reinstalling ALSA following the quick install guide (http://alsa.opensrc.org/Quick_Install) my soundcard is not recognized! It still shows up if I do lspci | grep Audio, and sound works on my windows partition... so it isn't broken... but I don't know how to get it back.


Any help would be greatly appreciated!

What does this give you?

How about this?

What does alsamixer tell you?

aplay -l, lspci -n, alsamixer
 

Output of aplay -l:

aplay: device_list:235: no soundcards found...

Output of lspci -n:

alsamixer:

cannot open mixer: No such file or directory

Leave it to run and open another terminal emulator. Run alsamixer and unmute everything, raise volumes until you hear sound.

Sorry, I meant '-k' instead of '-n'.

Are you sure you don't load the OSS modules somewhere? Have you rebuilt your initrd after uninstalling OSS? The module might still be ion there if you didn't. OSS conflicts with ALSA so it could stop the ALSA modules from loading, specifically snd-hda-intel.

What does this give you?

Reinstalled...
 

Given the time crunch I was in, I decided to just reinstall the OS. I was definitely loading the oss modules instead of the ALSA modules, but given that I had no files on that partition it was more straight forward to just wipe it and start from scratch. Thanks for your help!
