maybe this is redundant information, but the correct use of btsco is this:

1. start btsco <addr>

when it is ready connection to the headset (no more output), press the
headset "connect" button - some output like "open hwdep, connected sco
channel" should show up

keep btsco running! do not quit it!

2. use any audio app including aplay to play/record audio while the
headset is connected

3. disconnect the headset by pressing the "connect" button of the
headset again. Audio stops working until you "connect" again with the
button.

******

If you did everything like this, it should work like described. If it
does not, you might need another dongle :)

I'm using a epox bt-dg03 and it works fine for me, that is, for my
logitech mx900 bt mouse and my sony ericsson hbh-35 headset. I don't
know if this is the "best" dongle.

I was also able to use the headset with the "dongle" that came with the
MX900, but I never made much tests there (the headset is only used with
the epox dongle because I keep my IM programs running on that PC)

best regards,
~  Lars

| (btw: Should aplay ... be executed while btsco is connected

|

|
