[Bluez-devel] btsco and Nokia HDW-3 headset not working

[James Fitzsimons <james.fitzsimons@gmail.com>]

Hi all,

I am trying to get btsco working with my Nokia HDW-3 headset so I can
use skype from linux. I am can use skype under Windoze at the moment
with the headset and dongle so I know this setup works.

The thing is, I can connect and pair with the headset under linux. I can
even control the volume in alsamixer using the headset controls. I just
can't get any sound! For example if I configure XMMS to use the headset
as output it simply doesn't play.

I have included the following output suggested to assist with debugging
from http://bluetooth-alsa.sourceforge.net.

The output of hciconfig hci0 -a:

So I think this dongle should be fine right?

Now when I try to connect I get the following:

That last bit is me fiddling with the volume controls on the headset.
