hey guys I'm going to make you a quick video on how we can connect your Sonos Arc to the lgtv so first thing you want to connect Sonos uh at a Sound Source connect the HDMI cable to HDMI 2 then you want to press the gear on a remote to get the settings you then want to select all settings on the bottom sound sound out use wi speaker and you just want to select the HDMI ARC device then you just want to go back and select when settings and go to digital sound output pass through then you can have ER support you want to have on and then you're going to use a magic remote to control son's volume now then you're going to press the gear on remote to get the settings select all settings on the bottom wave there select General devices select external devices select universal control settings select hdma 2 select manage settings then you're just going to select boot Soundbar select Sonos manufacturer click through the finish at this point it still may need work use the Sonos app system select your system select TV up follow the prompts and make sure nothing else is connecting through the hdma and then follow the prompts until it's done so this is the one thing that you can try to do I just found this already maybe it's going to be helpful and uh I just saw here that if it's not going to work out you just want to disconnect everything from the TV including the arc and unplug the TV and Arc from the power for a couple of minutes then plug everything back in but keep everything disconnected enable siming on your TV then run the TV setup in the Sonos app under the arc settings and when the app instructs you to connect the arc to the TV's HDMI ARC Port using the Sono supplied HDMI cable so have a great day and goodbye
