Hey

> frontend is rarely the foreground app

So if avrcp were to present events in a /dev/input/eventX device, I
could use inputlircd to connect those events to lirc clients. It might
make it easier if a udev rule created something like /dev/input/avrcp0
so we could find it more easily for the inputlircd config.

And I see now that it is by virtue of the use of liblirc that myth can
get remote events even if it's not the foreground app.

Control is enabled by default in 4.60, is there anything I can check
to see why I don't see any log messages about avrcp, no input device
appear, nothing logged, etc? The main connection is initiated by the
headset and the audio connection is initiated by the computer. If I
remember tinkering with this stuff, bluez would need to initiate the
control connection in this case.

hcidump -X -V shows messages going across when I tap avrcp buttons...
