Hi Giuseppe,

Do you mean ending a call by closing the headset ??

Hmmm... strange. Could you please be a little more precise on that ?

I would even say 104 / 24 = 4,3333 time faster.

That's weird as xmms works really perfectly on my box. :-(
COuld you give me details about your software configuration (xmms 
version, alsa version, OS version..) ?

Could you also try to remove line 322 in file pcm_bluez_headset,
and see if it works better ?

Yep. It's on the TODO list. There is DBUS cabling to do (see dbus.c). 
Any volunteers ?? :-)

You're wrong on this one.
If you launch 'alsamixer -Dheadset' you will see your headset controls,
and if you play with volume controls while in a middle of a call you 
should ear the difference.

Cheers,

Fabien
