Hi there,

I have a bluetooth headset (Parrot Zik 2.0) which works (on my android). When I connect it to my desktop gentoo machine it
connects fine, pulse recognized the output device and switches to it. However there is no sound. The headset has a touch panel on the
right earphone, where you can give commands like pause, play and volume etc. When I touch this touchpad the headset plays sound.
So I looked into the recognition and the headset is recognized by xorg libinput (tail -f /var/log/Xorg.0.log:)

Code:

[  1431.539] (II) config/udev: Adding input device id:id:id:id:id:id (/dev/input/event20)
[  1431.539] (**) id:id:id:id:id:id: Applying InputClass "evdev keyboard catchall"
[  1431.539] (**) id:id:id:id:id:id: Applying InputClass "libinput keyboard catchall"
[  1431.539] (II) Using input driver 'libinput' for 'id:id:id:id:id:id'
[  1431.539] (**) id:id:id:id:id:id: always reports core events
[  1431.539] (**) Option "Device" "/dev/input/event20"
[  1431.539] (**) Option "_source" "server/udev"
[  1431.539] (II) event20 - id:id:id:id:id:id: is tagged by udev as: Keyboard
[  1431.539] (II) event20 - id:id:id:id:id:id: device is a keyboard
[  1431.539] (II) event20 - id:id:id:id:id:id: device removed
[  1431.547] (**) Option "config_info" "udev:/sys/devices/virtual/input/input27/event20"
[  1431.547] (II) XINPUT: Adding extended input device "id:id:id:id:id:id" (type: KEYBOARD, id 16)
[  1431.547] (II) event20 - id:id:id:id:id:id: is tagged by udev as: Keyboard
[  1431.547] (II) event20 - id:id:id:id:id:id: device is a keyboard


should the headset touchpad be recognized as a keyboard?

Hi,

you can check if some of your headset buttons are recognise as ACPI events. It's the case for at least one button with my H800 Logitech Bluetooth headsets. You can then program those events. Be sure that the acpid daemon is active and running, than use the command
Code:
acpi_listen

and press your headset buttons to know if the daemon recognise them as acpi events.
