added unity8 & bluez. Not sure who decided what keycodes map to what.

As of Bluez5, AVRCP does not inject keypresses any more, but bluez connects to MPRIS.

The issue is either in our bluez setup or the media-hub mpris interface

for me only volume keys work, not mute

This would be more than handy for demos

[Michał Sawicz (saviq)]

I don't think this is AVRCP actually.

These are likely standard media key events delivered to the shell that just passes them down to apps today.

[Simon Fels (morphis)]

It hardly depends on what the keyboard supports. Check via bluetoothctl which profiles it supports. If its only HID then its not AVRCP but otherwise it could and then we have to fix this differently.

The K480 reports:
Class: 000540
UUID: Service DIscovery
UUID: Human Interface Device
UUID: PnP Information

Status changed to 'Confirmed' because the bug affects multiple users.

Ubuntu Touch is no longer supported.
