[Bluez-devel] aplay freezes with headsetd

Hi,

I'm currently trying to get my "Logitech Mobile Pro II" headset connected
to my Debian box using the new and shiny headsetd. It seems that I get a
connection between my notebook and the headset when starting a test run
of aplay (the speaker of the headset is activated and emits some quiet
static sounds) but that's all that happens. Aplay will just kind of
freezes and that's it.

But now the information in more order (my CVS checkouts are from today):

Here I here, that the speaker has been switched on, but all I hear is
static.

root@washu:~ # hcidump -X -V
[*** shows a lot of stuff all the time similar to: ***]

~.7.=.0.F.Y.7...

The output of hcidump continued even after aplay didn't do anything
anymore.

I already tried to use the btsco method: Slightly different debug output,
but the same net result.

Any ideas?

Ciao
Florian
