Doesn't the Audigy provide a monitoring device, "capture" or so, that
you can select as source?

Well, silence is a good thing, broken amps and speakers aren't. IIRR
the ALSA docs clearly state that mixer channels are muted.
Back to the original question: Flash is closed soure, so if flash
doesn't provide a way to save the sound to a file, complains or
feature request should go to Macromedia.
Anyway if you run Mozilla through aoss you can get Flash run through
the ALSA system instead of the OSS emulation. Then it could be
possible to grab this stream with some asoundrc magic. You would
probably need to use some ALSA plugins I'm not that comfortable with,
namely "file". You should test this setup with ALSA software first,
that is use aplay to play a sound that is routed to a "file" plugin.
Example
Put this in ~/.asoundrc:
pcm.totalrecorder
{
type file
slave.pcm "default"
file "/tmp/recorder.raw"
}
Then try "aplay -D totalrecorder some.wav". This will record the audio
output to /tmp/totalrecorder.raw as a raw soundfile. You will need a
converter or an editor which understands opening raw files to make
this useful.
This should give you a start. Maybe someone with more insight can
complete this example.
For Flash you will then need to use aoss to be able to use the
"totalrecorder" device and you need to redefine pcm.dsp0 as described
in the manpage.
ALSA is an all inclusive package.
ciao
