Re: step by step - how to get your bluetooth stereo headset fully working with the bluez software stack under linux

I use Motorola S805 headphones as well. a2dp is so much better now than it
was a year or so ago that I've been somewhat happily living with it.

To add my experiences, audio only drops out when using other bluetooth
devices connected to the same computer. That is, I can use bluetooth in the
vicinity without interference, so it doesn't seem to be an over-the-air
thing. Also, I see the problem with my bt keyboard: even pressing a single
key can cause a drop while moving the mouse normally takes a couple of
seconds to mess up the audio. I suspect this has something to do with
changing connection state, but I don't actually know.

Also, the problem is far, far worse with high quality music than, say, a
poor quality book on tape. I almost never have a problem listening to voice
but always when listening to symphonic music. Perhaps it's compressibility?

I use both audacious and mplayer with identical results.
My system is very different from Jelle's: I have a low latency kernel with
upped jiffies and all that... it's gentoo-sources. Maybe observations on the
very different system will provide some clues.
