i use the xfce-pulseaudio-plugin in my panel (running xfce on debian buster). i would like for the keyboard volume controls to switch to controlling a bluetooth speaker when it is connected, but this doesn't happen.
on successfully establishing a bluetooth connection, the controls do nothing, and if i click the plugin, the output device displayed hasn't updated. to get my controls to work i have to open the plugin, hover over "Built-in Audio Analog Stereo" and then select my bluetooth device from the dropdown bullet menu that appears.
its only the controls that don't change. the audio output changes fine, and if i open 'audio mixer' (pavucontrol) from within the plugin it has correctly switched to the bluetooth device.
adjusting volume works there, or from the command line with
pactl set-sink-volume too.
basically i wd like my hardware controls to switch to working on whatever is currently outputting sound.
edit: i also have alsamixer installed, which i don't know anything about and don't know if is relevant...
