[Pkg-bluetooth-maintainers] Bug#618509: Acknowledgement ([bluez-alsa] no audio in headset)

[Török Edwin]

I've run hcidump on the system that won't play audio, and it seems its
sending all zeroes:

The other system where playing works, hcidump shows something else than
0 of course.

Also the headset doesn't show up in /proc/asound/cards, not even on the
machine where audio works

I'm doing all these tests with ALSA on both machines, I uninstalled
PulseAudio (because that wasn't working either).

I tried moving the usb bluetooth adapter (Conwise CW66222) to the
laptop, disable the internal bluetooth adapter, and I get no audio there
either.
However hcidump doesn't show zeroes anymore overthere.
