[Bluez-devel] Frequent headset disconnects

[John Feig <feig@nnytech.net>]

Hello,
I've been using the a2dpd app for a couple of weeks now, and really like 
it. I have a few issues though, with the main one being that after a 
couple of minutes of playback, my headphones (HT820) turn off, I turn 
them back on, and playback continues. I use these things long periods of 
time with my iPod and a Jabra a2dp adapter, I can listen for hours on an 
a2dp connection with those without interruption (aside from the 
occasional phone call). But within a couple of minutes using the a2dpd 
app (and amarok or mplayer), the connection gets really choppy, then 
drops out, and I have to turn _on_ my headphones. As you might guess, 
this is a show stopper for me, as I can't really enjoy listening to 
music wirelessly if I can't get through an entire song without turning 
my headphones back on.

Any ideas on why this is happening would be helpful, as right now, I 
don't even know where to start looking. Here's the output when it fails:
