Hello, I recently installed a USB bluetooth dongle with the intent of
using my Jabra BT500 headset in VOIP applications. I've followed the
Bluez audio service wiki with some degree of success; audio playback on
my headset works flawlessly with a variety of players. Audio recording
through the headset's mic, on the other hand, consistently stops
capturing audio after what appears to be ~250ms into the recording session.
I've tested this using both arecord and Skype's test call feature.
Running arecord yields
$ arecord -D bluetooth -f S16_LE
>boo.wav Recording WAVE 'stdin' :
Signed 16 bit Little Endian, Rate 8000 Hz, Mono
Aborted by signal Interrupt...
(manually stopped after several seconds)
The output file boo.wav is exactly 250ms long, and appears to contain
the very beginning of my recording. Skype similarly fails on the call
test (audio playback is fine, but the capture test fails to grab any
audio). In both cases, the Jabra makes the "call end" tone when I
finish my recording test. Also while recording, I get the following
system message several times:
hci_scodata_packet: hci0 SCO packet for unknown connection handle 45
Any thoughts on what the problem could be? Thanks for your help.

Excellent, I tried the bluez-utils cvs, and now both playback and
recording seem to be working. I'm not at home right now, so I
couldn't do an actual voice recording, but the headset mic seems to
record the noise of humming computer fans perfectly. XD
Thanks for your help!

A possible fix was just committed to bluez-utils cvs.
