In Sound Settings, I then have 2 entries: Built-in Audio Card and Logitech Adapter. The problem is that when I connect/reconnect to the bluetooth adapter, the sound volume knob is not bound to the Logitech Adapter. Instead, in Sound Settings, the Built-in Audio Card is selected instead of the Logitech Adapter. And when I use the multimedia keys on my notebook (Volume Up, Down, Mute), they have effect on the sound coming out of the notebook, not the external speakers. The expected result would be that, when I connect/reconnect the bluetooth adapter, the volume multimedia keys should bound to the new bluetooth setup, not the internal audio.
