[LAU] Audigy soundcard silent after upgrade to Ubuntu Studio

[David Morrell]

Hi,

I tried Frank's suggestion re muting / un-muting the Audigy Digital 
Output in alsamixer. It started muted before toggling.

I still could not play any audio, but there was a slight pop when I 
toggled it. It sounded like an amplifier turning on. When I turned the 
speaker amp gain flat out, I could just hear a bit of pinkish noise from 
the amp. Toggled the other way, silence.

I'll try Patrick's suggestion i.e. post to the developer list.

I've also found the ALSA Project page for the relevant driver at 
http://www.alsa-project.org/main/index.php/Matrix:Module-emu10k1. It 
leads one through installing ALSA and drivers from source. I have 
nothing to lose, so I guess I'll give that a try if I can't get anything 
back from the developer list. I don't want to mess up the system yet, 
though, in case someone wants debugging information.

Thanks for your help. Anyone else got ideas?
