So I am trying, and I got a little further, installing the right
lines into .asoundrc as per
http://wiki.bluez.org/wiki/HOWTO/AudioDevices. I have gotten beyond
issues of

  bt_audio_service_open: connect() failed: Connection refused (111)
  aplay: main:564: audio open error: Connection refused 

but it still doesn't want to work. If I execute

  arecord -D bt500v -f S16_LE | aplay -D bt500v -f S16_LE

then the headset makes a noise, the bluetooth LED flashes and
arecord prints

  Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 8000 Hz, Mono

But then after about 30 or 40 seconds, it all fails:

  ALSA lib pcm_bluetooth.c:464:(bluetooth_hsp_hw_params) BT_SETCONFIGURATION failed : Input/output error(5)
  arecord: set_params:979: Unable to install hw params:

I have bluez-audio installed, but /etc/bluetooth/audio.conf is
default. No PulseAudio or anything other than plain ALSA here...

Any clues?

actually I have none. It simply works for me. And I have tested it a
lot. There are some rare conditions where the btusb driver is off on the
16-bit boundaries, but I am looking at a fix for it. However this will
not disturb the audio service. You just don't here anything.

Regards

Marcel

Where should we go from here? How can I help debug this?

a cat has one tail more than no cat.

[Bluez-devel] "unable to install hw params" to bluetooth (SCO) headset (was: btusb+sco failing to play sound through Jabra BT500v headset)

[Stuart Pook]

Hello

I have read Martin's messages concerning his Jabra BT500v bluetooth headset.

I have similar problems with my Jabra JX10 headset.  I have installed 
bluez-4.4. When I run aplay with a 2.6.26 kernel, aplay works. When I 
run aplay with linux 2.6.27-rc5 I can hear a hiss when my PC connects to 
the headset but no music.

I have written a long bug report on 
http://bugzilla.kernel.org/show_bug.cgi?id=11514 with the output of 
hcidump -X -V and the messages from bluetoothd. Could someone have a 
look and give me a hint about what I might be doing wrong? Has anyone 
had any luck with Jabra headsets and 2.6.27-rc5 or should I buy a 
different brand of headset? Marcel Holtmann said that "It simply works 
for me." What headsets have you tested?

aplay always says "Unable to install hw params" after bluetoothd says 
"connect(): Connection timed out (110)" but hcidump shows lots of SCO 
packets being sent to the headset.

thanks
Stuart
