There appears to be no setting to disable sound effects for touch controls on the Move so when adjusting the volume of the output, you get a disturbing beep for each tap. The volume of the beep is tied to the volume of the device so the louder the volume, the louder the beep which is distracting given that it plays over the intended audio.
There are a couple of closed posts on this topic from >1y ago (indicating that this also affects other products than the Move) with an answer that says Sonos will refer it to their engineers.
Sonos, can something be done about this seemingly pointless (to me) function to at least handover control of it to the user?
