Hi there,
while running btsco I can successfully change my mixersettings via
the headset, so I assume the connection has been established just fine:
root@sigma:~/src/btsco# ./btsco -v 00:07:A4:95:41:76 2
btsco v0.4
Device is 1:0
Voice setting: 0x0060
RFCOMM channel 2 connected
recieved AT+BRSF=24
recieved AT+VGS=03
Sending up speaker change 3
recieved AT+VGS=07
Sending up speaker change 7
recieved AT+VGS=11
Sending up speaker change 11
recieved AT+VGS=15
Sending up speaker change 15
speaker volume: 15 mic volume: 1
driver is in use
connected SCO channel
Done setting sco fd
But I can neither hear sound nor record anything via the Jabra BT110
headset using BlueZ 20050328 with kernel 2.6.11:
aplay -D plughw:Headset test.wav
Playing Sparc Audio 'test.wav' : Mu-Law, Rate 8000 Hz, Mono
I just hear a raise in static when playback commences (even though mixer
levels are maxed in alsamixer!)...

you can try latest kernel 2.6.11.x
This works for me.

For me is SCO connection opened from xmms or from mic
"cat </dev/dsp1 >/dev/dsp0".
Both works simultaneously.

I don't know what other I can tell you. For me it's working.

Dear Pavel Ruzicka,
I am also involved in testing the BT Headset functionality with the
PC. I am using a CSR based USB BT Dongle on the PC and the BT Mono
Headset is the RFMD Headset kit.
I have taken the latest CVS "btsco" files and compiled. Fedora 3(linux
kernel 2.6.9-1.667) runs on my host PC. I have taken the latest Bluez
libraries and utilities from the bluez site.
After running the "btsco" I am able to run the xmms and play songs and
test for the speaker functionality separately. But I am not able to
test the Sound recorder functionality. The SCO connection is opened
only when I press "play" for the xmms and it closes when I stop the
song. Whether I can test the mic functionality separately.
But my target application is a chat application with the usage of
Speaker and mic working simultaneosly.
Please advice of the setting I need to make.
Thanks & Regards,
Benny

Hello,
I now tried compiling snd_bt_sco for 2.6.11.6 and everything works great.
I am using btsco 00:07:A4:0A:3F:XX or btsco 00:07:A4:0A:3F:XX 2 and both
works.
I have headset Jabra BT250.
Dongle is d-link DBT-120 with 1.2 firmware.
This sents sound from headset mic to soundcard:
"cat </dev/dsp1 >/dev/dsp0".
Simultaneously I start xmms, setup out to BT headset alsa device, and
mp3 plays in my headset. Sound from headset microphone goes to my normal audio
set.
I have few questions:
Audio is heavily delayed (about 300-400ms)
What is the reason for this delay?
Sound from microphone is noised. For speaking is enough, but quality is not
much good. Is it normal?
Best regards,
Pavel Ruzicka

I hate to say it but it looks like you're doing everything right, the
adapter seems to be good, etc.
I haven't heard success stories for using the bt110 but I can't remember
if we've had trouble reports on this one or not.
> root@sigma:~/src/btsco# ./btsco -v 00:07:A4:95:41:76 2
The only thing I would suggest is that you don't specify the channel
here, but I suspect btsco will autodetect channel 2 anyway.

look at the window you get when running "usbview" or try to read
/proc/bus/usb/devices and you can see how things connect.
if your usb/bluetooth adapter is plugged directly into the computer, you
should get the ohci chip. at least that's how it is on my toshiba m200.
