SCO Socket input connection.

Hello.

I'm developing embedded alarm system with hands free bluetooth profile.

Some months ago this code in python was working OK. (i don't remember
bluez version)

self.sco = socket.socket(socket.AF_BLUETOOTH, socket.SOCK_SEQPACKET,
socket.BTPROTO_SCO)
print "socket SCO opened."
self.sco.bind("00:00:00:00:00:00")
self.sco.listen(1)
sck, mac = self.sco.accept()

When receiving a call on my cell phone and took down (via rfcomm HF
connecton) , SCO connection was produced from the phone to pc.

Now this connection fails.

I added to audio.conf   Disable=Headset,Control,Gateway    to disable
SCO Listening from bluetoothd but with no result :(

The only thing that works is to launch this python code before bluetoothd.
Some thing is touched by bluetoothd  that blocks SCO incoming
connections for other apps. ¿What?

I try  compile with --disable-audio with no results.

Thanks. and sorry for may horrible English.
