Re: After 2.6.38 upgrade I have no sound

it found only 1 of my audio outputs (hdmi on the videocard, and i don't use that one).
After i cancelled alsaconf, i did alsactl store and that removed the error alsa gave on starting.

Re: After 2.6.38 upgrade I have no sound

ok, this is what happened on my system :

after the lastest kernelupdate , from 2.6.37.5 to 2.6.38.2 alsa gave errors on boot and i decided to see what alsaconf reported.
alaaconf only saw 1 of my audio cards (and the one i don't use) , so i canceled alsaconf.
"aplay - l" and alsamixer did show all my my audio outputs, and sound was working.
(with alsamixer you can also switch between your sound devices).

I ran 'alsactl store'     (as root) , at next boot the errors were gone.

it's likely this only works if you already have a working configuration.

if this doesn't help you, please post the output of the following commands :

aplay -l

lsmod|grep '^snd' | column -t

ls -l /dev/snd
