So I'm going with a bad jack. Because repair can be too high for most we offer an USB sound replacement. Our tech has something like this handy (you can find these all over.)
That's 3 or less bucks for a thing like that.
Hello everybody, I am trying to connect my laptop so my Sony HiFi system via 3,5mm to 2 RCA cable into Aux In Jack on the stereo,and it only plays one speaker, the other is just buzzing... Then I connect RCA cables(red and black) in reverse, other speaker starts to play, but still the other doesn't work. When I connect my phone this way to stereo system, both speakers play perfectly. And headphones plugged into computer play good(both ears). So anybody can help me? Why does only one speaker in stereo system works, when connected to laptop?
P.S. I changes RCA cable several times.
