Problem with bluez and a bluetooth headset

Problem with bluez and a bluetooth headset

[XazZ XazZ]

good evening everyone

Few days ago I got a new, beautiful bluetooth headset.
It's a Nokia BH-503
My PC got an "ID 1131:1001 Integrated System Solution Corp. KY-BT100
Bluetooth Adapter"
For the usb dongle part from lsusb -vv check the link at the bottom (lsusb)

Sadly I'm having some trouble getting my headset to work with my PC.
Neither I can play music over my headset nor can I record something over it.

When I'm trying to record sound via `arecord -D plug:bluetooth -f
S16_LE test.wav` I get the following output:
Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 8000 Hz,
Mono
ALSA lib pcm_bluetooth.c:464:(bluetooth_hsp_hw_params)
BT_SETCONFIGURATION failed : Input/output error(5)
arecord: set_params:1022: Unable to install hw params:

PERIOD_BYTES: 2000
PERIODS: 4
BUFFER_TIME: 500000
BUFFER_SIZE: 4000
BUFFER_BYTES: 8000
TICK_TIME: 0

skype tells me:
ALSA lib pcm_bluetooth.c:1619:(bluetooth_init) BT_GETCAPABILITIES
failed : Input/output error(5)

I've added a link to bluetoothd's logfile when trying to record via arecord
(link name is bluetoothd.log)
I also added bluetoothd's logfile when trying to do the sound
test in skype (link name is bluetoothd.log.0)

The bluez version I'm running: 4.17

I also tried to get my headset working with bluez 3.32
with 3.32 I could play music over my headset - but I could NOT record sound.
I googled and some people came up with the fact that pulseaudio might
break bluetooth sound: I do not have pulseaudio installed or running

I also tried changing the bluetooth section in my ~/.asoundrc
I changed profile to: "voice" then to "hifi" and then to "auto" -> it
never worked

In my dmesg I get "hci_scodata_packet: hci0 SCO packet for unknown
connection handle 2" and "hci_scodata_packet: hci0 SCO packet for
unknown connection handle 65398"
according to jhe from IRC: <jhe> that error sounds like its sending
SCO packets without having informed the host (bluez) that there's a
SCO connection
NOTE: its == my bluetooth dongle

Earlier I also got some stack traces - but I couldn't reproduce those
on a non-tainted system yet:

As soon as I'm able to reproduce on a non-tainted kernel I'll post an update

If you need more information please feel free to ask - I'll post it as
soon as I can.

Thanks in advance

good evening again

I got one step further after deleting my whole bluetooth-configuration
and setting everything bluetooth-related up from scratch :)

I got audio output on my headset working.
Audio input (recording) is sadly still not possible

bluetootd says the following when trying to record audio:
a2dp_source_cfg: no available SEP found
config failed

skype and arecord say the following as soon as I try to record audio:
ALSA lib pcm_bluetooth.c:712:(bluetooth_a2dp_hw_params)
BT_SETCONFIGURATION failed : Input/output error(5)

You can get the full bluetoothd log here: http://nopaste.ch/64aa1a77e7813e4.html

I also noticed that I can neither play nor record something when I set
profile "voice" in ~/.asoundrc
When I set it to profile "hifi" audio playback works fine.

Thanks for any help in advance

I've got that same exact dongle on my desktop. It can't talk to my 
headset either, or my phone, or my laptop, or a Wiimote. I suspect it 
has issues with the new btusb in 2.6.27. I can list devices, but when I 
try to pair, it just waits until eventually the following appears in dmesg:
hci_cmd_task: hci0 command tx timeout

I had that dongle working in an earlier kernel version. On 2.6.27, my 
laptop's Bluetooth is working fine.

Okay, I tried this again.
As soon as I change "profile hifi" to "profile voice" sound playback
stops working

[XazZ@darklight ~]$ hciconfig hci0
hci0:   Type: USB
       BD Address: 00:11:67:8F:29:0E ACL MTU: 1021:8 SCO MTU: 48:10
       UP RUNNING PSCAN
       RX bytes:2487 acl:33 sco:0 events:110 errors:0
       TX bytes:2126 acl:36 sco:0 commands:65 errors:0

That suggests that no sco packets have been sent (although there
should have been one)
I also get two hci_cmd_task: hci0 command tx timeout in my dmesg as
Brian Rogers said

Again the output of bluetoothd -nd:
http://nopaste.ch/502c8ee33709a6d.html (I hope it helps)
Maybe my device needs some quirk?

Oh, and I'm using the btusb driver which comes with 2.6.28 rc3 (Brian
Rogers uses the same driver)

good evening

I'm already running a kernel which is newer than 2.6.27 (I'm currently
running 2.6.28 rc3)
But something else must be wrong then:
my USB dongle is a 2.0 one and my headset is also a 2.0 device

[XazZ@darklight ~]$ hciconfig hci0 version | grep HCI
        HCI Ver: 2.0 (0x3) HCI Rev: 0x2c6 LMP Ver: 2.0 (0x3) LMP Subver: 0x2c6

that's what my hciconfig says about my dongle

That is directly taken from my headsets manufacturers website (Nokia)
