No sound with Intel HDA (ATI SBx00 Azalia, Realtek 887)
I upgraded to squeeze last week, and finally rebooted yesterday. My sound is no longer working since the reboot: things like audacious2, aplay, speaker-test run without any errors, but I can't hear anything. I've checked that my speakers are ok, and that none of the channels are muted (alsamixer).
00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA)
(the card is sometimes also referred to as Realtek 887)
alsaconf seems to run successfully, and finds my sound card, then adds entries to /etc/modprobe.d/sound:
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
, and to /etc/modprobe.d/alsa-base.conf:
options snd-hda-intel model=generic
I've tried lots of things to get sound working. Someone suggested compiling alsa from source (to get the latest version), but that didn't help. I've tried various different model= parameters for the snd-hda-intel module, but generic seems to be the most suitable. Just now I've upgraded from squeeze to wheezy/testing, but that hasn't solved it either. Very frustrating, since it was working nicely in lenny.
Any ideas please?
