Bluetooth Audio service

Hi,

I'm trying to configure my Motorola H500 headset to work with my Arch install. I'm acting accordingly to this wiki: http://gentoo-wiki.com/HOWTO_use_a_blue … _and_newer

My bluetooth works well, I can pair with my phone, use HID device (again, phone with remote control), but I can't get the headset to work
I can detect the device using both kbluetooth and hcitool:

Scanning ...
        00:19:1F:05:1A:3F       Motorola H500

I can even connect to it:

hcitool cc 00:19:1F:05:1A:3F
hcitool con
Connections:
        < ACL 00:19:1F:05:1A:3F handle 43 state 1 lm MASTER

I've modified files pointed in the wiki:

cat /etc/bluetooth/audio.service
[Bluetooth Service]
Identifier=audio
Name=Audio service
Description=Bluetooth Audio service
Autostart=true

cat /home/neuro/.asoundrc
pcm.bluetooth {
   type bluetooth
   device 00:19:1F:05:1A:3F
   profile auto
}

But when I try to play a file I get:

mplayer -ao alsa:device=bluetooth filemp3
MPlayer dev-SVN-r24986-4.2.2 (C) 2000-2007 MPlayer Team

I don't know, but I thought that should do it and it shoudl work. Any ideas? Could someone tell me how to debug the thing?

Re: Bluetooth Audio service

Ok, something moved on after the recent update of bluez.

The headset now pairs when I try to play something back on it, connects, however there is no sound and mplayer says:

[AO_ALSA] alsa-lib: pcm_bluetooth.c:460:(bluetooth_hsp_hw_params) BT_SETCONFIGURATION failed : Input/output error(5)
[AO_ALSA] Unable to set hw-parameters: Input/output error
Could not open/initialize audio device -> no sound.

In this thread (http://ubuntuforums.org/showthread.php?p=4637238) I've seen someone talking about a patch for the kernel (http://lkml.org/lkml/diff/2008/2/25/530/1). Is this patch already applied in 2.6.24?

EDIT:
I've just seen in message.log that something gets logged:

May 18 20:58:10 deck hcid[13943]: Audio API: sending BT_SETCONFIGURATION_RSP

Any idea why sending sound fails after this?

Re: Bluetooth Audio service

Interesting if you got it solved in the end. So far bt audio in ArchLinux seems completely broken.

keep in touch.
