[mythtv-users] Lost audio over hdmi - mythbuntu 10.10 0.24.1-fixes

[John Haywood]

Since a power outage recently, followed by some minor repairs, my Mythbuntu 10.10 no longer outputs sound.
Indeed, if I run aplay -l, I get :

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

I have a suspicion that it might be missing modules:

lsmod|grep -i snd
snd_pcm                89104  0 
snd_seq_midi            5932  0 
snd_rawmidi            22207  1 snd_seq_midi
snd_seq_midi_event      7291  1 snd_seq_midi
snd_seq                57512  2 snd_seq_midi,snd_seq_midi_event
snd_timer              23850  2 snd_pcm,snd_seq
snd_seq_device          6912  3 snd_seq_midi,snd_rawmidi,snd_seq
snd                    64277  5 snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device
soundcore               1240  1 snd
snd_page_alloc          8588  1 snd_pcm

seems to be missing what I need for my board:

Gigabyte E7AUM-DS2H, which has an onboard nvidia :

This box has worked well since 0.24.1-fixes, so I wouldn't mind getting it running (and the associated WAF) again. I recall Jean-Yves has/had the same board, so if he's reading this I'd appreciate any input

cheers
