Well I take it all back!
I was in the middle of a game of Glest when the sytem crashed and I was not able to boot into the new kernel even after trying booting off the Ubuntu CD and doing a Gparted check. I had to boot into 2.6.31 and remove 2.6.32 via Synaptic. Dang. That was really nice having decent sound for 30 min.

Highpitched Rattling like Sound with 5.1 Surround Configuration on Karmic Koala

Status in “pulseaudio” package in Ubuntu: Confirmed

Bug description:
Binary package hint: pulseaudio

I'm hearing a high pitched rattling sound when I have pulseaudio set to 5.1 surround
I set PulseAudio to 5.1 surround via the PulseAudio Volume Manager under the Configuration Tab
I'm running the Karmic Koala beta with all the newest Updates
I have a 82801JI (ICH10 Family) HD Audio Controller

I've tried other settings under the Configuration Tab, Analog Stereo seems to work perfectly but I have a 5.1 Surround Speaker Setup.

This problem seems to get worse as I increase the volume through pulseaudio, if I change the volume of a individual channel it gets almost impossible to listen to anything, all I can hear is a high pitched rattling like sound. However if I set the volume of channels individually through 'alsamixer' it doesn't screw up at all.
