So I have a TX NR585, a friend of mine gave me an old sub he had stored in his house and I remember using it just fine for 2.1 if I wanted to listen to music using the receiver's Spotify app. I disconnected after a while because it was an old HT in a box model so it wasn't very good and was doing more harm than good.
Fast forward to today and I've got a new SVS SB 1000 pro, I installed it, reactivated the sub in the receiver's speaker config, and for some reason, it doesn't actually come up as an option in any of the listening modes while using Spotify. Even Dobly and other full system modes (And yet the other 3 speaks show up just fine, just not the sub). I'm attaching a pic for reference
Thing is, when using say, Netflix, it shows up just fine. Any ideas? I know I must be missing something in the config menu, just can't figure out what
