First of all, hello everyone on this forum! First post! I'm really really pissed off about this. My 8 week old MBP won't send audio to the right speaker. I've got the headphone output going to a left and right RCA adapter which goes to a NAD amplifier from the 80's which goes to my speakers. There is absolutely nothing wrong with this hardware because it works with my phone and old laptop. I've tried absolutely everything. Played around with the panning in audio settings, played around with panning on the amp, tried every random pair of earphones and headphones I could find and plugged them directly into the computer, unplugged and re-plugged everything and of course turned off and on absolutely everything. All to no avail. I seriously need some help, it's so annoying just hearing everything in the left ear only. Thanks!!!
