I'm using my HBH-DS970 headset with a2play, and it works nicely. However, I would also like o use the daemon functionality of the btsco key daemon at the same time, so as to control playback with the headset butons. Is this possible?

well it might be possible for you to hack something together using the btsco settings file.

if your headset supports avrcp, you should be able to use the alsa plugin and a2dpd daemon to control playback. that would be more flexible.

According to the docs I need a2play to play stereo, since the HBH-DS970 supports stereo. Has this requirement changed? It would be much nicer wih a proper alsa device of course.

I tried the a2dpd daemon as per Brad:s suggestion, but Im having difficulties. The build and install went ok.

This is my configuration:
~/.asoundrc

pcm.headphone {
              type a2dp
              bdaddr "00:16:B8:0E:8B:15"

cmdplay=echo play
cmdnext=echo next
cmdpause=echo pause
cmdprev=echo prev
cmdnew=echo cmdnew
logfile=/tmp/a2dpdlog

then I start a2dpd

then I test with:
mplayer -ao alsa:device=headphone 01.mp3

alsa-init: using device headphone

So something goes wrong

a2dpd has this to say:

Thanks for spotting this!

Some problems remains:
- the sound is much "choppier" than with a2play
I suspect this line from a2dpd output:
setscheduler returns -1 (errno=3D1:Operation not permitted)

must I run a2dpd as root?

- I only get sound in 1 earpiece, the sound is very soft in the other one.

Some problems remains:
- the sound is much "choppier" than with a2play
It should not be that bad, try another audio player ( xmms/amarok/xine/mpg321 )

Hi,

Quoted 9 lines

It seems I can get the AVRCP commands to work "sometimes"(for some unknown definition of "sometimes"), so my headset appear to support it.
so , current problems are:
- I dont know how to make AVRCP commands work reliably, or how to debug it. I think maybe some command has to produce output to the a2dpd daemon for AVRCP commands to be received.

A2DPD can run some commands to control a mediaplayer remotly. Xmms provide such features. It is player dependent and can be customized in .a2dprc.

My old headset behave differently depending whether it was receiving sound or not :
When not receiving sound, it did not do AVRCP at all, but it tried to establish an A2DP connection. So the daemon received this incoming A2DP connection, close it and launch the media player, wich in turn will make a new outgoing A2DP connection to the headset.

When playing, the headset will send normal AVRCP commands.

- xmms output is really choppy, whereas mplayer output is ok. I tried fiddling about with xmms alsa settings, like mmap and buffer settings and whatnot, but no real breakthrough.

Do you send 44100 Hz stereo? It's the only supported format. Other format need conversion.
