I have an optical plugged into a hearing aid box. I also have an LG S95QR sound bar plugged into the eARC.
Works fine in eARC. When I try to select the optical + TV option for output, it switches over ok for about .5 seconds, then automatically switches back to the eARC output without me doing it.
Does anyone know what it might do this? Why can't I change my output if I so choose?
