Hi Loki,

Thanks for the quick reply!

"Sound out of the iMic"... do you mean bypassing the USB port?  should
I be able to test the mic input using the phones output?  (I'm not in
front of it @ the moment, but I had the impression it was either
mic-to-USB, or USB-to-phones)

everything that can be turned up in alsamixer is turned up.  I never
have had very good luck messing with alsa though; and was mostly
trusting that to this freshly-installed ubuntu :^(

I think the snd_*_oss modules are alsa's oss-compatibility thing, not
oss itself?

There is an instance of esd running, might that get in the way too?

The sound is a little funny in other ways, w/XMMS for instance, the
GUI volume slider doesn't have an effect; nor does the PCM slider in
aumix, I have used aumix's Volume to adjust it.  Also, when I open
audacity from the menu, the Gnome desktop makes a silly little noise &
causes audacity to not be able to initialize the appropriate device

I found an ubuntuforums howto called "Happy ALSA, OSS, ESD, with
Duplex - Sound Settings", I'll try going through that this evening

Thanks again,
Kenneth
