if you really unmuted *everything* in alsa mixer that was a bit to much.
In fact when you unmute the loopback option you should be able to hear
the recorded sound echoed back to the headset, but you can not
record/play anything else meanwhile. so do not unmute "loopback". If
that's not the problem I'm a bit lost :/

what kernel? is it 2.6.10 with mh1 patches from bluez?

| Hi everyone,
| I've been trying to get my headset to work lately, with partial
success: using the latest btsco-cvs, I manage to connect to the headset
(a Jabra-250, I think), and pressing the volume/answer buttons is
correctly detected by the program. I've unmuted everything in alsamixer,
and set  snd cards_limit=2 in modules.conf (although I don't use modules
for alsa...). Everything is as it should be, except I can neither record
nor playback anything. Here's my dmesg after pressing the play button
three times on xmms (the progress bar doesn't move, the song doesn't start):
