I have the same issue. Sonos Playbar. One button command for mute and unmute. But sofabaton only gives you the option on selecting two buttons for the functions. This is a major issue for any Sonos Playbar owner. Please adjust so mute/unmute can be assigned to a single button. Sonos OS: S2 Series ID: A100 Hardware version: 1.9.1.10-1.2
