Subject: USB-audio strange problems
Hi!
Ok, so it took me a year to get back to this bug. Oops.

I got the usb soundcard to work. I still have IGNORE_CTL_ERR enabled.
Problem was not mixer after all... somehow it expects me to play sound
as 8-bit, and then I can play 16-bit mono and actually hear
it. _Strange_.
So:
mplayer -ao alsa:device=hw=0 -af format=u8 KDE_Startup.wav
mplayer -ao alsa:device=hw=0 -af format=s16le -af resample=48000 -af channels=1 KDE_Logout_1.ogg
...plays both files.
Forget about the first mplayer, and it will play nothing.
