I was connecting my home theater into my LG TV via optical and realized on my fire stick that it was mono audio. So I grabbed my laptop and plugged it in and went to manage audio devices. When configuring TV audio it only displayed 2 speakers (my front left and front right) under a stereo configuration and it didn't see my subwoofer dispite it working just fine. I don't know what is wrong and I can't find something in settings which can fix it (perhaps it's a problem with my reciever) but I do know something is wrong.
My reciever has 2 settings (stereo and six channel) and no matter what it plays out of the back left on the fire stick but it I select 6 channel then no audio plays out so I think the problem is that my TV doesn't have 6 channel audio support because I can't find output settings on my TV
