I'm experiencing weird things. When I plug my headphones into one of my N900s, then I don't get a headphone icon the status bar. Still
1) the headphone inserting event is recorded in dmesg
2) psswitcherd recognizes this as well - when I insert the headphones, the loudspeaker gets disabled.

The same headphones work perfectly on another N900 and a computer.

Any ideas what's happening? I'd rather avoid reflashing - I've just flashed 2 weeks ago and have spend a while getting my perfect setup :P
