I just got around to playing with the ubt(4) I've had plugged into my 
Netra T1 for a few months the other night, and I've had just about the 
same experience with recording... however, playback works now and then. 
 Actually, recording doesn't even get silence, the output file is just 
32 bytes long (I presume that's just the AU header; man how soon we 
forget these things ;)).

About one out of 3 or 4 attempts at playback attempts actually produces 
sound, but that sound comes ~ 20 seconds+ after the 'audioplay' 
invocation.  The rest seem to fail with 'audioplay: audio drain ioctl 
failed: Resource temporarily unavailable'.

My 'bthset' instance will also occasionally die with a 'Connection lost' 
message.  It's easy to restart, but kinda annoying when it does lose the 
connection.. this might be related to fact that I've got other devices 
which are paired to the headset in the vicinity and they might grab the 
devices' attention.

Config is the same as yours (hw.ubt0.config=2 & scomtu=48); my headset 
connects on channel 1.  My headset is a Plantronics Voyager 510 
(PLT-510), which has worked with a bunch of other PCs / handhelds / 
phones without any problems, and the USB dongle is a TrendNet TBW-101UB 
(which worked fine with the headset when connected to a WinXP machine). 
 This is all with 4.99.64 from ~ 5/28 on sparc64.
