Help!
Problem : Clipping noise - Volume goes down and up fast randomly

Not HD and hard to see but you should be able to see those 3 windows :
1) alsamixer : Surround, Center, LFE and Side goes to 0 and backup to 100 in a split second
2) pavucontrol : Output Devices / Port : this one switches to Headphones and back to Analog Output very fast
3) KDE / System Settings / Multimedia / Phonon / Audio Hardware Setup / Device Configuration : Here it's the Connector that is switching to Headphones then back to Analog Output very fast
I uninstalled alsa and pulseaudio, same problem. I uninstalled kmix, problem disappear but I don't have sound anymore. I booted with Linux Mint 14 (both Mate and KDE), same problem right on the LiveCD. I have a dual-boot setup with Windows 7 and this one doesn't reproduce the same problem so there's no problem with my speakers or the cable.
This is my motherboard : http://ca.gigabyte.com/products/product ... id=4139#sp
This looks like the same problem : https://bugs.launchpad.net/ubuntu/+sour ... ug/1067434
This one also : http://superuser.com/questions/519874/s ... d-behavior
Any help is appreciated. For now my fix is to simply reduce to the minimum the sound of my speakers and raise to the maximum the volume in KDE, the clipping noise is barely noticeable that way.
