Hello,

I'm not sure I'm supposed to be posting here, but on bluez.org both
the development and user mailings lists point here.

I'm having problems getting bluetooth audio (a2dp) to work without
stuttering, skipping, speeding up etc. I'm using bluetooth speakers
(Creative D100). It works okay if it is right next to my laptop, but
when I touch the speaker or move it more than about 1 meter, it starts
stuttering.

I have the D100 and haven't noticed such a problem.

The bluetooth adapter is a Broadcom BCM2070 (which is a class 1
adapter). I'm using kernel 3.1.5-1.

I've tested it with the Bluez 4.96, and I've also compiled 4.97 but
it's no better. I've tried using Alsa and PulseAudio, the problem is
the same with both.  I've tried adjusting the link mode
(accept,master) and link policies (hold,park) as recommended but it
makes no difference.

What version of PulseAudio are you using? This problems with audio
skips are usually related to high bitpool, but there already exist a
fix upstream which reduces the bitpool in such cases.

When I dual boot my laptop into Windows 7 and connect the speaker it
works flawlessly. I'm able to take the speaker through 2 rooms (about
10 minutes), and it's still playing smoothly.

Not sure what bitpool Win 7 uses, but I suspect it is not as high as
the default in PA which allows up to 64 if the remote device supports.
