Hi Fred,
I used the headset with a lot of alsa apps like
gnomemeeting, mplayer, aso, and non alsa apps thru the
oss emulation of alsa.
For gnomemeeting this is just fine because is also
intended for voice, but to listen to a movie on a 8KHz
mono headset is not so HiQ.
Anyway it realy works.
What I am trying to do is to connect it when I press
the button on headset and disconnect it when I press
the button again. So no need for special applet.
I think that will be nice to put some support for
btsco in kdebluetooth, but the right person to ask is
not me.
Maybe Brad or Lars can give more details of what is in
the future development for btsco.
I just modified btsco a bit to be able to use the
rfcomm connection accepted by kdebluetoothd and did
some other small changes to better fit my Jabra BT110.
Anyway, if I can help with something, just let me
know.
Thanks,
Paul

Just a few comments that where not even asked for :)
just to describe whats happening right now:
we have a small "daemon" that does the whole rfcomm and sco connection
handling (btsco). It listens on rfcomm for the connect/disconnect events
from the headset (button press) and opens/closes sco when needed.
the second part of the whole lot is snd-bt-sco, which handles the
sco-to-audio transmission. This thing will be reworked sooner or later,
we hope it can be a user-space driver AND we want to get rid of the data
transfer loop by connecting alsa and sco socket directly (or converting
the sco socket).
What I always thought about was some way of "communication" between our
btsco daemon that does the connection handling (also should manage
different headsets and stuff like auto-connection on audio-open later),
and I think you might have some suggestions here, Fred.
i.e. an application like gnomemeeting might like to open the headset, or
a tray app could display the status of the headset. For this, the daemon
must support some "connection" thingy. How should this be done? I never
did something like that before, so I don't know... :)
Maybe something simple in /proc or /dev? We won't need much mojo there,
just control for each headset (on/off)
best regards,
~ Lars
