I have a 65 SK8000PUA tv and a pioneer vsx-80 receiver. I have a very nice 7.2 setup with MK speakers and a dual throw sub. I can use the receiver with my PS$ and get great hd Audio through my receiver, but when I use the ARC from the LG tv I only get stereo which is annoying because I watch everything through my TV. WE are YouTube TV, Netflix, and Disney+ watchers. I have change the arc settings in the LG set up to be simplink on and sound output to Auto just like every thread I have seen says to do. Am I missing something that would allow my audio to be surround instead of Stereo?
