Dear Vladimir Botka,
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.
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
