Hi again...

well, now it seems to work, but I have no sound : it is like the voice=20
packet are not sent to the headset.

1) info about the headset

Using Debian Sarge, with a patch for bluez from march 2005. Got btsco=20
form cvs. Compiled without error. Seems running ok. When using XMMS, I=20
see a second audio device "bluetooth headset", I see it with alsa and=20
with OSS output plugin. If I try to play a song with XMMS, I hear a=20
"beep" indicating the activation of the SCO channel. I can see it with=20
"btsco -v", verbose mode. I also can adjust the volume of my headset :=20
it's echoed on the output of btsco. On the other side, if I use the oss=20
mixer, I hear a small beep in the headset and see that the volume is=20
changed accordingly to the mixer on the computer. Same for microphone.

So (I'm BT newbie...), the "signalling" seems to work perfect *BUT* no=20
voice packet are sent. HCIdump shows the "signalling packets" but after=20
that, no other packet. with XMMS, if I "play", the song remains still=20
(time stops). Just the beep in my ear to say that the channel is opened=20
(I hear the same under WinXP when I accept to "connect" the headset,=20
pushing on the "answer" button of the headset), and another beep when I=20
stop the song and thus, "disconnect" the SCO channel (again, I see all=20
that with btsco -v and hcidump).

When I will get it , I will resume the whole thing for configs like=20
mine. Help me get the sound work :-(

thanks

Laurent
