David,
Here's my /var/lib/alsa/asound.state file. You can try moving yours
aside by renaming it, and dropping this in to see if it makes any
difference. I have the Audigy2 card in this ArtistX/Ubuntu 9.10 Dell

Amazing! Eureka etc. Thanks very much indeed, Frank. I've put about 15
hours into this problem and you've solved it. Now the question is, how
did a bad asound.state file get created as a default during
installation? Does anyone know where I should go to alert someone who
can look at this?
Here is a comparison of the good and bad asound.state files.
The replacement asound.state file has 227 controls vs 216 for the oroginal.
The following 14 switch controls existed only in the good file.
The Master Playback Switch only existed in the good file. If it exists
on the sound card and is muted by default, there would be no sound output.
There are 3 possible duplicated controls.

New subject: Audigy soundcard silent after upgrade to Ubuntu Studio

Excellent, David! I'm delighted it worked and was that simple.
As far as the non-functional setup goes, this card is a little flaky - I
mean, that inconsistency in the D/A jack switch alone is illustrative of
that. There are a number of mutes present and countless sliders, many
of which have unclear functions with conventional stereo output, and all
it takes is either something to be muted - or un-muted in the case of
that D/A jack and the particular buggy kernels - or something to be slid
down, for there to be no sound for a given input/channel.
David,
Here's my /var/lib/alsa/asound.state file. You can try moving yours
aside by renaming it, and dropping this in to see if it makes any
difference. I have the Audigy2 card in this ArtistX/Ubuntu 9.10 Dell
Workstation, and it is fully functional.
Amazing! Eureka etc. Thanks very much indeed, Frank. I've put about 15
hours into this problem and you've solved it. Now the question is, how
did a bad asound.state file get created as a default during
installation? Does anyone know where I should go to alert someone who
can look at this?
Here is a comparison of the good and bad asound.state
files.
The replacement asound.state file has 227 controls vs 216 for the original.
The following 14 switch controls existed only in the good file.
The Master Playback Switch only existed in the good file. If it exists
on the sound card and is muted by default, there would be no sound output.
Hmm, that's worse than I suggested above. Well, maybe not. Once you've
executed alsamixer for the first time - and realize, this card may not
be properly "awakened" via one of the desktop environment's GUI mixers -
and exited, the asound.state file should be updated, but just to be
certain, I'd execute a sudo alsactl store command. Do a stat
/var/lib/alsa/asound.state to see the time stamp to ensure it's a fresh
write.
So, maybe the core code is not entirely to blame for this problem.
There should be a post-inst script that does all this, and I believe the
alsamixer CLI application accepts arguments to set the channel mutes and
levels, but if any distro leaves that out - and it of course wouldn't be
executed unless the Audigy was detected - it's going to be up to the
desktop, or the GUI mixer app, or the user to "wake up" the card when
first used.

New subject: Audigy soundcard silent after upgrade to Ubuntu Studio
Here's the next instalment. First, the background.
The problem was that a Creative Audigy2 card that had worked perfectly
in Ubuntu 8.04 suddenly went silent after an upgrade to Ubuntu Studio
9.04. It still worked perfectly in Windows on the same dual boot machine.

Delete /var/lib/asound.state (to mimic a fresh install, when it has not

Run
alsactl init
The sound card is probed. Alsactl reports;
Unknown hardware: "Audigy2" "SigmaTel STAC9750,51"
"AC97a:83847650"
"" ""
Hardware is initialized using a guess method
A version of asound.state is created that lacks (at least) a master
volume mute switch. There is no sound output.
Restore the previously good asound.state, run 'alsactl restore' and the
card works again.
Does this mean that something (I don't know what) needs to be improved
so it can recognise this card (Audigy 2 Value [SB0400)?

David,
My understanding was that the functionality/setup of the Audigy driver
was buggered in the 9.04 J.J. kernel module. Once you've fiddled with
alsamixer, and created a working /var/lib/alsa/asound.state file it
should be fine. I believe this is fixed in the 9.10 K.K. version.
