i have 2 polk T50 speakers, one on the left and one on the right side of my desk. i also have a polk T30 center speaker, with a PSW10 10 inch sub all connected to a Pioneer VSX-530-K 5.1 Channel AV Receiver. Managed to get all of it working at one point, but a couple days ago we didnt have internet so i swapped it to bluetooth audio and it worked fine, but when i swapped it back to my pc audio the right speaker stopped working. if i swap it back to bluetooth it works fine, ive tried changing the cables and nothing has worked so far.
