I installed an ARC with 2 OneSL speakers on my DirecTV satellite system a few years ago with no issues.  I had to replace my internet home gateway and DirecTV set top box just recently due to a bad electrical storm in the area.

DirecTV sent a technician out after I replaced the fiber gateway to replace my set top.  The video works fine, buy I cannot properly reconnect my Sonos system after running through the DirecTV remote set up menus.  I’ve made several attempts, and had their technical support on the line during these attempts.

The ARC is not listed on DirecTV’s audio set up menu list, and I’ve tried all other choices with no luck.  Any help this forum can offer will be greatly appreciated!
