Thanks for the feedback.

Yes, the uinput module is loaded and I've tried with alsa alone and with alsa+pulseaudio

At the first remote AVRCP key press, I see this in dmesg:

input: 00:1B:66:00:31:88 as /devices/virtual/input/input11

..and if I run bluetoothd in the foreground, I see (for example):

bluetoothd[4253]: AVRCP: uinput initialized for 00:1B:66:00:31:88
bluetoothd[4253]: AVCTP Connected
...
bluetoothd[4253]: AVRCP: BACKWARD pressed

But there is no corresponding action in rhythmbox
