I discovered the solution to my question, but it gets deleted as spam.
i posted a question a few days ago regarding my MacBook A1342 right and left speakers, and finally discovered the solution today.
I tried to post the answer for my own question, but it has been deleted (by moderators?), with negative reputation points included. I would like to have my answer restored, the negative reputation points removed, and to be able to accept my answer as the solution. could someone help me? Thanks so much.
