Did not help. I made following:

- modprobe snd-bt-sco
- headset is switch off
- btsco 00:0b:2e:06:01:2e
Device is 1:0
Failed to connect to SDP server: Host is down
Assuming channel 2
- I swith on headset, information above is completed by
Voice setting: 0x0060
RFCOMM channel 2 connected

So there is communication between my usb BT adapter and the BT Headset.=20
But still nothing more. When I run

mpg123 --au - <MySongFile>.mp3 | /usr/src/btsco/sbc/sbcenc - |=20
/usr/src/btsco/a2play 00:0b:2e:06:01:2e

still have

MPEG 1.0 layer III, 128 kbit/s, 44100 Hz joint-stereo
subbands =3D 1
allocation method =3D 1
channel_mode =3D 2
blocks =3D 3
sampling frequency =3D 2
bitpool =3D 32
frame len =3D 72
Using address: 00:0b:2e:06:01:2e
Can't connect to 2E:01:06:2E:0B:00. Invalid argument(22)
cannot open psm_cmd =3D 0

Ok, this I got. It's the same manipulation as if you want to enter the=20
PIN code for pairing. And I got:
nomade:# hcitool scan
Scanning ...
        00:0B:2E:06:01:2E       BT1000

So everything concerning connection seems to be fine but I still can't=20
see any traffic going through! Has someone an idea on what is this=20
invalid argument error (22) with a2play?

Thanks for your help
