I'll assume this buzzing is coming from your speakers.
Are you hooked up via HDMI or 3.5mm?
If you are hooked up via 3.5mm then chances are you may have a grounding issue. I had this problem with my laptop to a small extent when hooked up to a 3.5mm. It was too loud and sounded just like static. I was able to make it quieter (relatively) by turning up the volume on the computer all the way and controlling volume in XBMC (with +/- or a remote that controls it in XBMC). When you turn up the volume of your TV (or AVR) the sound probably gets higher, that's why you would turn up the rest of your machine first.
Unfortunately I do not have this problem with my setup, and I will note I am hooked up via HDMI (which sends a digital signal as opposed to analog of 3.5mm jack).
One more option would be to get something that acts as a ground to get rid of the static noise, just search for computer grounding buzz or something along those lines, there are some solutions out there.
To summarize some solutions:
Connect via HDMI if you aren't already
Turn up volume of your computer as much as possible before turning up your TV/AVR
Get something to help ground your device
