I'm trying to get btsco to work with my headset.  Thus far, I've managed
to solve my first problem of having to reinstall ALSA libs; got
everything to compile and run fine.  btsco even starts and looks to be
running correctly.  HCIDUMP shows it connects correctly.
When I go to play a sound file, the device makes a distinctive sound
(incoming call style sound (wav file being played I guess corresponds to
the same sound)) I can hear the speaker in the headset turn on.  When I
stop playing a sound, the speaker turns off.  However, no sound is
actually played.


Anyone have a suggestion for what to try next?  Thanks in advance for
any help.

I have a motorola HS820 and a CompUSA USB Bluetooth Adapter
