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.
