First post and new user.
I have the Sonos Arc (and gen 3 sub and dual SL rears) connected to an LG OLED C9 via eARC and HDMI 8K 2.1 cable and hard wired Cat7 Ethernet (Orbi WiFi 6 system). With both DirecTV and Apple TV I have started to get audio cutting out for a FRACTION of a second randomly. I have power cycled and made sure all have up to date software. I will remove the WiFi password tonight as recommended by Sonos when hardwiring. I have Dolby Digital/Atmos set to automatic.
Any other ideas?
