I have the 32 bit Windows 8 Consumer Preview installed in Boot Camp with the Boot Camp drivers generally working fine, but there's an audio issue. If I run iTunes and play music in the background, after 5-10 minutes I get interference, it sounds like the digital audio isn't working and iTunes freezes up. It's certainly not a hardware issue - everything works fine in OS X with the same MacBook and headphones. Anyway to sort this? Or is it just a bug in the Windows 8 beta I have to wait to be fixed? I couldn't find other people having the same issue when I googled.
