Hi,
until recently I was easily able to send regular audio output to my BTH12 headset,
which stopped working sometime around or shortly after the 2013/2014 break.
The BT applet in the tray shows it is connected to the headset, the headset beeps
as connected but sound goes to regular loudspeakers only. Headset also beeps when
I disconnect using the applet.
>From the syslog I am not sure where the problem is, some error messages are from
bluetoothd, another from pulseaudio and kernel.
# hciconfig hci0 up
has the effect that "Bluetooth: hci0 command 0x0407 tx timeout" appears in syslog
and some delay.
# hciconfig -a
