Send sony Vol/mute commands to XBR and TV displays vol level. Set speakers to off, output fixed and popup shows "vol is fixed".
With Sonos playbar and no control system, I normally set Xfiniity or Directv remote to random amp and teach playbar. Works great until customer wants to use factory remote to access Amazon from TV.

Just did a room with a Snap mini amp, XBR850 - Xfinity the only source. Same story - set xfinity remote to send amp vol commands. Works great but customer wants to use Sony remote for Smart TV.

Sony tech support didn't have a solution. Anyone know if the vol popup can be disabled?
