Re: Upgrade bluez-4.17 to 4.36 - headset no longer works

[balaji palaniswami <balaji_palaniswami@yahoo.com>]

Hi John ,

I got same problem when updated to 4.36.
I got error 
ALSA lib pcm_bluetooth.c:(audioservice_expect) .....
ALSA lib pcm_bluetooth..c:(audioservice_recv) Bogus message ....

I could not remember exact error message.but it is similar your message.

In bluetooth daemon log ,
i got BT REQUEST < BT GET CAPABILTIES 
Invalid message length 

In code , i checked message header length is zero.hence it terminated client socket.
Then i assumed that problem is with alsa , so i reinstalled bluez-* packages and rebooted.

i tried aplay to play a song it started , immediately i aplay pcm write error mesage.so i concluded that its problem with aplay . i tried rythem music box in Ubuntu 8.10 .Finally , I heard song in Motorola 850 Headset.

 Thanks,
 Balaji.P

No feedback? Something basic must be wrong if a bt headset won't work...

Hi,

I recently upgraded from bluez-4.17 to bluez-4.36 and now my se hbh-610 headset no longer works.

Any pointers would be gratefully received.

Thanks, John

This ~/.asoundrc used to work:

Quote
pcm.bluetooth {
type bluetooth
device "00:12:EE:A6:1D:F4"
profile "auto"
}

ctl.bluetooth {
type bluetooth
}
Unquote

..with the following:
$ aplay -Dbluetooth -f S16_LE /usr/local/share/sounds/alsa/Noise.wav

..but with bluez-4.36, there is no sound and "bluetoothd -n" reports:

bluetoothd[7621]: link_key_request (sba=00:21:86:E4:4D:67, dba=00:12:EE:A6:1D:F4)

I tried the .asoundrc suggested in /etc/alsa/bluetooth.conf:

Quote
pcm.rawbluetooth {
        @args [ 00:12:EE:A6:1D:F4 ]
        @args.00:12:EE:A6:1D:F4 {
                type string
        }
        type bluetooth
        device "00:12:EE:A6:1D:F4"
}

pcm.bluetooth {
        @args [ 00:12:EE:A6:1D:F4 ]
        @args.00:12:EE:A6:1D:F4 {
                type string
        }
        type plug
        slave {
                pcm {
                        type bluetooth
                        device "00:12:EE:A6:1D:F4"
                }
        }
}
UnQuote
