I have this MacBook Pro on my bench that I have already fixed, hard short on a SSD rail, but it also has another issue. the right speaker sound is either earrape, muffled or absent. Left one works perfect. I have tried replacing it, nothing changed so I'm pretty sure the issue is either motherboard related or maybe software but I doubt that.
I don't how to troubleshoot speakers. Any help would be very much appreciated.
A refurbisher and a repair shop have already been inside the laptop but I'm pretty sure none of them tried to do any soldering on the board.
