The issue I'm having is that the speakers only play from one side until I turn the volume knob up, and then it comes out balanced. I could live with this issue but there's some other wonky stuff happening too. Sometimes, I'll turn the volume knob and then it will remain constant even if I turn the knob up and down. So, even with the knob turned all the way down, sound will still come out. I'm not very versed with this kind of stuff, but any idea what the issue is?
