Thanks! that's exactly what I'm doing every day, I use headphones too and plug/unplug them very frequently. I also never shutdown the mac, I just put it to sleep by closing the lid.

I've been doing the same for years with the old MBP (regularly coming to 30 days uptime without any itch) and always considered this the best feature (bulletproof sleep) that keeps me from going back to linux.

PS Ironically enough, just after posting my first comment the mac freezed up again...
