[Feature request] Adjust volume of USB connected speakerphones with their physical buttons

[TB-SE]

I know there are options for playback volume in the Assist Microphone add-on configuration, but I can't get them to work. I tried putting 0.5 in the playback volume option, but that didn't work.

Would be nice if we could use the buttons on the speakerphone.

The only physical button that works is the mute button for the microphone, but that is to be expected since it toggles a switch within the unit.

I'm using the Anker PowerConf S330.

The volume setting is not stored for me either, same for the VAD setting (and possibly other). They're just set back to the default after restarting the add-on.

The volume works, use the correct value: X,Y (X comma Y) not X.Y (X dot Y)

Oh, thanks! Not sure why I didn't think of that before. Works perfect. Still would like to use the buttons on the unit.
