Found that thread earlier while searching, but unfortunately the problem described there is different. My headphones work fine, even if connected after the game starts.

Also tried the suggestion in the last post on that thread - no joy.

Edit: ARGH. /facepalm, etc. I had the 'vibrate' button switched on. Since music plays fine, I haven't noticed until someone called me. Hi, From searching this forum, as far as I understand, sound should work both over speaker and over the headphones. Is that correct? I only get sound when hooking up...
