High pitched noise from one channel when playing sounds

First of all, here's the problem. When playing any sound I only get good sound from one channel, the other channel plays but emits a loud high pitched buzzing/squealing sound the entire time the sound card is being used (and for a few seconds afterwards).

I'm running on an amd64 and started out with edgy amd64 and had the problem there. I decided I wanted some newer packages (and hoped maybe the problem had been fixed) so I upgraded and I'm now running Feisty amd64 yet the problem persisted. Thinking it might be a amd64 related problem I booted to a livecd of edgy i386 yet had the same problem.

Poking around on google I found someone else who had a similar problem and their fix seems to be working for me (haven't had any time to test it extensively) for the moment.

Their solution was to add this line to /etc/modprobe.d/alsa-base
"options snd-hda-intel index=0 model=3stack position_fix=0 single_cmd=0"

I'm not sure which option is fixing it, but now sound plays properly from both channels and no high pitch squealing sound. As I said, I'm running Feisty right now with a 2.6.20-9 kernel for x86_64. I don't know if this fix works for edgy (but I would assume it might).

The module it's using for sound is snd-hda-intel (I tried the snd-VT82xx module but that left me with the system not finding my sound card)
