Hi,
I'm trying to connect a Plantronics 590A headset to my Debian machine
with a D-Link DBT-120 (B2) USB dongle. But bluetooth-alsa isn't working
for me. I followed the instructions here:
http://bluetooth-alsa.sourceforge.net/build.html
I can get as far as pairing the headset with the computer and running
a2dpd. But in XMMS I don't get an "a2dpd" option for ALSA output. Can
anyone tell me what I'm doing wrong, or what I should do next to debug it?
I have set up my ~/.asoundrc as instructed:
pcm.a2dpd {
type a2dpd
}
But no ALSA device seems to be available. aplay only sees my M-Audio
Delta 44:
mexon@aeon:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: M44 [M Audio Delta 44], device 0: ICE1712 multi [ICE1712 multi]
Subdevices: 0/1
Subdevice #0: subdevice #0
Here's the output of a2dpd. There's an error in the second line, but I
ran an strace and it looks like the file not found is "/tmp/a2dp.pid",
so that should be OK:

Here are my answers to the questions on the contact page. The only
thing I haven't done is try SCO, because I don't want to patch my
kernel. If there's no other way to debug this, I'll probably just give up.

* I'm already using plugz
* I'm not trying to use SCO. So this doesn't apply to me. Right?
* I do have bluez-passkey-gnome installed (version 0.5-2, Debian Etch).
* I don't think I'm using an old bluez version (libbluetooth2 is version
3.7-1, so is bluez-utils).
* I did pair it with another device, then I tried the re-pairing
procedure. I can only make it pair if I run hcitool info, which is
interesting. I also have to delete the headset from my linkkeys file
for this to work. But now that I've figured out this procedure, I have
no problem pairing.
* Eliminating the hub made no difference.
* Headset is Plantronics 590A:

* I don't have any other adapter or headset.
* I don't have "choppiness", I don't have anything at all. So this isn't
relevant, right?
* I don't get this error.
