Option to disable volume OSD overlay when using eARC with external audio system

When audio output is set to eARC (external soundbar/AVR), the projector still displays its volume overlay bar on screen when receiving CEC volume commands. Since the projector isn't handling audio in this mode, the overlay is unnecessary and disruptive during content playback.Please add a setting to disable the volume OSD when audio output is set to eARC. Many users with external audio systems (Sonos Arc, AVR receivers) connected via HDMI processors like HDFury VRROOM are affected by this.Device: HORIZON S MaxFirmware: latest
