Sometimes I'll play a song and it will cut out every 10-20 seconds and sometimes the whole song will play through without problems. I didn't know if that was my headphones' fault or the tablet.

Right now I'm looking at the output that mplayer gives me about alsa-init and it seems like my desktop is using a different buffer size when playing to the headphones then my Nokia is using. I don't know if that's something that's set by the actual ALSA driver in the kernel or something set by mplayer though. Or maybe it could have something to do with the bluetooth dongle used, but I *do* actually have a way to test that. More later...
