So basically I have Logitech 2.1 speakers that have the sound control knob and I've had no problems with them until right now. When the knob isn't at full volume, sound comes out of the right speaker mainly and barely out of the left speaker. If the volume on the knob is all the way up it re-balances. This is something that is normal when I plug headphones into the sound control knob, except it only plays out of the left side of the headphones, not the right, but has never happened with the actual speakers. Any fixes for this?
