hi everybody,

it's some time I'm trying to get my BT headset to work with btsco, but
with no results.

the problem, which I found reported but not answered in a forum on the
bluetooth-alsa sourceforge project page
(https://sourceforge.net/tracker/?func=3Ddetail&atid=3D678259&aid=3D10679=
46&group_id=3D116589),
is I can connect to the headset (see log above), set volume from pc, see
events, and even hear a hissing sound, but I can't hear any sound using
aplay, nor record anything; the programs just hang.

I hope this issue is not an already well known and solved; if so it is,
please redirect me to where the info I need are, thanks.

Else, here are some logs as suggested to report; I omitted the output of
`hcidump -x` because it is very long, but I can of course provide it if
necessary.

thanks in advance for helping me.

BT dongle: Trust BT180 (USB, works fine with other devices, like my T39
phone)
BT headset: Ericsson HBH-35 (works fine as phone headset)
