Colin, thank you, that just turned on so many lightbulbs. I'd run pavucontrol a bunch of times, but nothing seemed incorrect from just looking at the GUI. Following what you just said, I ran it with sound actually playing in vlc at the same time, and lo! more stuff showed up. This was completely non-obvious to me, that to make pavucontrol do anything, you had to have a stream going at the same time. > pavucontrol also let's you set the "default" sink, so that brand new > streams will go through your preferred device by default. This does not I tried to look for that in pavucontrol, found nothing, and then ... The second lightbulb was that right-clicking on this in pavucontrol would be a good idea. Again, completely unexpected. Right-clicking, in my experience, is usually used in editing docs (OOO, GIMP, Inkscape, etc.), but not in "control panel" kinds of places. > apply to applications that have already played as they will be > remembered as perfering the device they were first played on (IMO this > is suboptimal and there should be a concept of "default" built in to the > stream remembering stuff - this will come eventually I'm sure).

I'll look at daemon.conf. What's the GUI in Mandriva? Is it not upstream? ;) So, gnome-sound-properties shows the Audigy2 as having 3 outputs: ADC Capture/Standard PCM Playback (ALSA) Multichannel Playback (ALSA) Multichannel Capture/PT Playback When I tell g-s-p to use Standard PCM, it says: audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink profile=music: Could not open audio device for playback.
