Hi,
I have recently installed LG G2 screen along with SONOS AMP and both are connected via HDMI ARC on HDMI port 2.
i have 2 x HDMI sources (Apple Tv & Dish Tv) which are connected with the LG screen by using HDMI port 1 & HDMI port 2.
Once SONOS amp configured properly with the LG screen but after a couple of minutes mute showed on the LG screen and audio muted. in this scenerio if i select the TV speakers, sound comes from the tv speakers properly but on ARC it gets muted.
Then i unplug the Dish tv HDMI and after couple of seconds sound comes from the ARC.
Please advise.
