Bluetooth Headset connection issue with PulseAudio

Bluetooth Headset connection issue with PulseAudio

[Benjamin Vasanthakumar J]

Hi All,
I am trying to connect my bluetooth headset to my Linux box using Pulse 
Audio. I am able to successfully run the pactl sink command but when I 
look at the debug log I could see the headset is connecting and 
disconnects immediately due to an error returning unknown connection 
handle in the SCO packet.

My test configurations:
Linux Kernel version : 2.6.30
Bluez version : 4.32
Pulse audio version:  0.9.14
Linux Distro: Ubuntu Jaunty 9.04

My BT Dongle: Gigabyte BTD02
HCI Ver: 1.2 (0x2) HCI Rev: 0x639 LMP Ver: 1.2 (0x2) LMP Subver: 0x639
Manufacturer: Cambridge Silicon Radio (10)

Pulse audio, pactl sink command output is as below:
btaudio~$ sudo pactl load-module module-alsa-sink device=btheadsetsudo: 
unable to resolve host btaudio
15

I am getting the following error in the kernel message:
hci_scodata_packet: hci0 SCO packet for unknown connection handle 45

Please find the log of "bluetoothd -nd":
bluetoothd[4127]: Unix client disconnected (fd=13)
bluetoothd[4127]: State changed 
/org/bluez/4127/hci0/dev_AE_2D_CC_AA_BB_14: HEADSET_STATE_PLAYING -> 
HEADSET_STATE_CONNECTED
bluetoothd[4127]: No matching connection found for handle 45
bluetoothd[4127]: telephony-dummy: device 0x2064d398 disconnected
bluetoothd[4127]: State changed 
/org/bluez/4127/hci0/dev_AE_2D_CC_AA_BB_14: HEADSET_STATE_CONNECTED -> 
HEADSET_STATE_DISCONNECTED

My asoundrc file:
btaudio:~$ more .asoundrc
pcm.btheadset {
type bluetooth
device AE:2D:CC:AA:BB:14
profile "auto"
}

Anyone has come across this similar issue? Any suggestions.

Thanks & Regards,
Benjamin

There are 2 kinds of bluetooth modules in pulseaudio. The 1st one sends
the audio via alsa-bluetooth and the the 2nd one are the native
pulseaudio bluetooth modules. None of them are working AFAIK.

But, there is the possibility to use the bluetooth headphones and be
able to use the pulseaudio. Use the following .asoundrc

# cat ~/.asoundrc
       pcm.!default {
               type pulse
       }
       ctl.!default {
               type pulse
       }
       pcm.btheadset {
               type bluetooth
               device "00:13:17:72:CD:FF"
       }

Thus all default alsa output is redirected to the pulseaudio and the
bluetooth headphones can be used with the applications which allow to
select specific device (btheadset in this case). You can find more
details here [1].

Thanks for your reply and the details on the asoundrc file.
We could hear only some sound at regular intervals. There is no Music 
heared.

Is there anything to do the version interoperability?

My test configurations:
Linux Kernel version : 2.6.30
Bluez version : 4.32
Pulse audio version:  0.9.14
Linux Distro: Ubuntu Jaunty 9.04

Does the following error cause the issue that I am facing? 
bluetoothd[3977]: audio handle_uuid: server not enabled for 0000111e-0000-1000-8000-00805f9b34fb (0x111e)

Thanks & Regards,
Benjamin

There is no audio.conf in my /etc tree. The
bluez-audio is configured here /etc/alsa/bluetooth.conf (attached).
Tarball /etc/bluetooth is attached too. But, telephony-dummy is a2dp
device ? Try with other a2dp (stereo) headphone. Maybe [1] can tell
more. And try a simple "aplay -D bths foo.wav" for testing (where bths
is your entry in ~/.aosundrc.

I have same bluetooth.conf file.

I had one audio.conf in the /etc/bluetooth which I deleted and tried. 
The device connects
in HFP and only noise we could hear.

I do not have a stereo headphone. I have a mono headset that supports 
HSP. When I play
using aplay -D btheadset <music file> I get the following error.
/Playing raw data 'Nagada Nagada.mp3' : Unsigned 8 bit, Rate 8000 Hz, Mono
aplay: set_params:961: Sample format non available

/But when I played using the following option
aplay -D plug:btheadset <music file>
the file is playing, I hear only noise.
