DSB1/DISH

homerj

I have a DSB1 system connected to my Dish Hopper3 , LG television, and Roku on the side. All been fine for a few years until last night. Was casting from pc to TV like usual and had the sound coming out of Polk. All of sudden sound cut out on its own. LG sound out was set to HDMI ARC. Dish and Polk Bluetooth link disconnected from each other. took a while to figure out but got Bluetooth reestablished. BUT NOW....Dish ONLY will come through Polk. If I run the Roku, the Dish audio still comes through Polk and I have to change LG audio to internal speakers and turn down volume on Polk/Dish. WHAT HAVE I MISSED OR WHAT DO I DO TO RECONNECT EVERYTHING BACK TO POLK? Thanks for any advice you can provide!
