Constant noise on right channel (snd_via82xx)

There is on constant noise on the right channel. It starts after beeing logged on gnome.

I have seen another user with the same problem on the forum and since he is using the same audio controler as me I tought it might be related to it.

I try adjusting the master and pcm levels but it doesn't fix the problem. Completely shutting down the right channel doesn't fix the problem either.

Steps to reproduce:

Do a fresh install of ubuntu on a system that use a VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 10).

Log on to gnome.

You should hear a low to high pitch noise on the right channel.
