Hi Andrew,

Are these 3 assumption valid at the same time?

- Hcidump does show the connections
- a2dpd does nothing at all just sits there looking pretty
- AVDTP(s): Discover rej: transaction 0

If these three points are absolutly true at a time, then you have another s=
oftware answering the bluetooth connection. It's not an a2dpd as the main t=
cpsocket would be busy. I thought it wasn't possible but I can't see anothe=
r point since you have an answer that a2dpd do not display. Curiously, this=
 software also reject the avdtp_discover as do a2dpd. Aven't you forgotten =
an a2recv or any other bluetooth software in your startup scripts? It may b=
e kde or gnome-bluetooth related too I don't now what they do with a2dp...

Try the following to make sure :

# a2dpd MUST NOT be running
killall -9 a2dpd
sudo hcidump L2CAP

Then connect your headset normally (Pressed play 2 times from switched off =
headset switched on then pressed play), you should see the following :

HCI sniffer - Bluetooth packet analyzer ver 1.28
device: hci0 snap_len: 1028 filter: 0x8
> L2CAP(s): Connect req: psm 25 scid 0x0041                         <------=
---------------------- The headset wants to connect to psm 25
< L2CAP(s): Connect rsp: dcid 0x0000 scid 0x0041 result 2 status 0 =

    Connection refused - PSM not supported                          <------=
---------------------- Refused as nobody listen that psm

If the connection is accepted we will know that a2dpd do not answer, now we=
 must find who.

open a root shell and type 'ps uax' to see all running processes
then for each pid try 'kill -9 pid' until you find the good one :D


Hope we get it one day :D
