With enough metadata so we know that the volume change is caused by us pressing
a key. This would allow us to report volume changes through an OSD for
Bluetooth headsets.

<coling> hadess, I wonder if we could send an event to you for notifying when
volumes are changed via bluetooth (or just generally, but with sufficient
metadata that you can filter out the ones you yourself have triggered etc.)
<coling> hadess, this same mechanism could be used to display the OSD with the
new volume when plugging/unpluging jacks etc. (I think you are against this
idea generally from our discussions in Berlin which is fine, but at least then
a neat infrastructure would be there to allow it).
<coling> <coling> Or course you can technically already subscribe to sink
change and see volume changes but you wouldn't be certain they came from the
keys, hence why something a bit different would be needed.
