What I wrote is wrong. Your headset supports both S8 and U8, but the USB audio driver uses the wrong format. If you have the source, you can fix this by editing alsa-kernel/usb/usbaudio.c: in line 2005, change U8 to S8, then recompile and reinstall the drivers . (This fix should be in CVS in a few days.)
