A customer brought in a MacBook Pro A2991 M3 Pro with a serious audio issue:
โก๏ธ Background noise on the right side
โก๏ธ Right speakers missing mid and high frequencies
โก๏ธ Only distorted sound output
After a detailed board-level inspection under magnification ๐ฌ, we identified the root cause:

Our repair process:
โ
