My SoundStick 2 does not play ANY sound from the speaker with the Plus/Minus tabs!! Tabs do indeed work and I can Mute/Unmute the entire system! However, no audio sound comes OUT of this speaker! I did test the speakers with 2 other MacBooks in addition to the Win 10 PC and the symptoms are the SAME! No sound from one speaker. Is there a way to reset the logic board?! Any ideas or suggestions would be greatly appreciated.
