Hi there,

After a smooth upgrade from 7.10 to 8.04, I don't have sound anymore.

Alsa is still installed and the snd-hda-intel is detected, but impossible to have sound.

I have rebuilt & reinstalled alsa drivers, but still not working ... I have tried passing option
Code:
options snd-hda-intel model=imac24
in /etc/modprobe.d/alsa-base, but this does not help

Is there a way to find where the error is? There is an entry in /proc/asound for a Realtek ALC885 card ...
