[Bluez-devel] A few tests: a2play aborts when hanging up the call. That's not the way it should work.

[db]

I've made some tests with 2 recent stereo headsets : the Jabra 620s and the =
Com1
(a french company) headset.
I've noticed the following things with the Jabra and the Com1 headsets.

While listening to stereo music with a2play, taking a call works (that the p=
art
of the headset) and the a2play keeps on to stream during the call. Normal.
But when I hang up in order to go on and listen to the music the a2play dete=
cts
a connection reset by peer and aborts.

I made the same test with a QTek 9100 (HTC Wizard is the same device) and
whatever the headset: when I hang up the music stream goes on but on the
internal speakers of the Qtek not on the headset.

I made the same test with the A2DP emitter that comes with the Com1 headset =
and
with this device the stream goes on on the headset (Jabra or Com1).
What I want to say is that the a2play (or alsa plugin) code SHOULD be more
reluctant to abort depending on the kind of error.
Maybe could we introduce a kind of L2ping in order to see if the device has
vanished.

My 2 cents,

My best to all the team,

Are these sets doing avrcp? It's possible that your headset likes to
send a pause command via avrcp to the a2dp streamer before taking the
voice call. If so, we should listen for avrcp pause and act accordingly.

I should probably combine a2play and avsnd but for now, start up

 avsnd <headsetbtaddr>

just after you start up a2play and watch the avrcp stream.

can you try this again by running "a2play -p" from cvs? I believe that
listening for messages on the control connection *during* playback was
where we were missing this, not in avrcp as I originally thought.
