volume control doesn't work for bluetooth headset

[Ákos Maróy]

Hi,

After I've connected my bluetooth headset (see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1782893 ), it seems the volume control doesn't work. e.g. if I adjust the volume in settings / audio, it doesn't have an effect on the headset volume. if I adjust the volume on the headset itself, the difference in volume is not reflected in the control panel (e.g. the slider doesn't move)

what I would expect is that the volume setting at the headset and in the settings menu are in sync, and these two set the 'same' volume
