Everytime I switch Wifi on while I am using my Sony BT DR101 Headphones the sound gets unlistenable, very distorted. I was HOPING Apple might fix it in 3.1.1, nope it's worse than ever. Anyone else having bum luck with A2DP and Wifi? Stranger yet, my iMac has horrible A2DP sound too, unless I use Softick Audio Gateway with it. Tried a couple different brand headsets, no luck.
