Re: No sound problem ?



Andy,
This is looking more and more worrying !!!
This has been an ongoing problem for me for quite a while. I cant remember 'exactly' what other solutions I have tried, but it did involve attempting to recompile Alsa modules.

Hey.
Really appreciate this bit of help !

system-config-soundcard gives this output :

Oh dear.  Can you look in /var/log/messages for unknown symbol info, eg

tail -n50 /var/log/messages

Did you unsuccessfully recompile the Alsa modules using the alsa-project.org stuff?

What does

modinfo snd

say?
