I decided to try bluez-4.2 with my Jabra JX10 Bluetooth headset. I ran bluetoothd. It says that it has registered interfaces for org.bluez.network.Router, org.bluez.network.Hub, org.bluez.network.Peer and org.bluez.serial.ProxyManager but nothing about an audio service. It does load the /usr/local/lib/bluetooth/plugins/audio.so plugin. The python script bluez-4.2/audio/test-audio says "org.freedesktop.DBus.Error.UnknownMethod: Method "ActivateService" with signature "s" on interface "org.bluez.Manager" doesn't exist".

Running arecord just says "BT_GETCAPABILITIES failed : Input/output error(5)".

I created /etc/bluetooth/audio.conf and modified my ~/.asoundrc.

What else do I need to do to get bluetooth audio working?

I am running linux 2.6.27-rc5 because I want to try the new btusb driver and it's SCO over USB support.

In

I saw that bluetoothd can say "Registered interface org.bluez.audio.Headset on path /org/bluez/hci0/dev_". Does it have to contact the bluetooth headset before registering the org.bluez.audio.Headset interface?

When I run bluetoothd, dbus-monitor --system says " interface=org.bluez.Manager; member=AdapterAdded".

Any help would be most welcome.

thanks
Stuart

PS I also tried creating /etc/bluetooth/rfcomm.conf but I don't really know what to put in it.
