Public bug reported:
Binary package hint: pulseaudio
Since i upgraded to Karmic, my 5.1 sound output on my creative labs extigy USB
card is broken.
The previous release did work with alsa, and was working fine.
Now with Pulseaudio, the sound is only working correctly with stereo output,
with 5.1, the sound is crackling, and the pitch is too high.
