Public bug reported:
Binary package hint: bluetooth-alsa
In Gutsy Server edition and using bluetooth-alsa 0.5cvs20070602, I'm
experiencing issues streaming audio from a dongle to an audio receiver /
headset device. After quite some time getting things connected and
working (it was fairly difficult without a GUI), I get good quality
audio for brief periods of time followed by intermittent loss of sound
(~2-3 seconds at a time). When I boot into Windows XP using the same
dongle (ASUS) and headset and stream music, the problem never occurs. I
had the same problem with a previous completely different dongle /
headset combination I was using previously.
Whether I use the pcm.A2DPD device or the pcm.bluetooth device doesn't
seem to matter -- I still get intermittent loss of sound.
The only error messages that I can find are long streams of the following in
/var/log/syslog:
l2cap_recv_acldata: Unexpected continuation frame (len 0)
