Hi Brad,

I am successfully using my jabra BT110 headset with gnomemeeting which
supports alsa natively. For now gnomemeeting supports only H323, but it
will do SIP in the near future.

But I also tested with linphone which only supports OSS, and the
oss emulation worked for me (used /dev/dsp1 ).
I tested with linphone version 0.12.2.

Works very well with a Sony HBH-35 :)

Yes I use gnomemeeting with alsa at the moment but I haven't had time
to get my headset working properly under Linux.

There is a snapshot for the pre alpha SIP/H323 version of gnomemeeting
here http://snapshots.seconix.com/cvs/ although I can't get OPAL to
compile under FC3 so I haven't actually tried it yet.

Hi there,

I think you use snd-bt-sco, don't you? This should of course work,
because snd-bt-sco is no user-space alsa driver, but runs in kernel
space, so oss emulation works. It uses the headset profile, not a2dp.
(fancy stereo audio stuff) :)

Or am I wrong? I thought there's no alsa support for a2dp yet.

best regards,
~ Lars
