Well my 2019 Macbook pro right speaker has joined with all the others. Sounds like it is blown, but I don't listen to it at full volume, and last I used it, it was fine. Upon firing it up tonight and going to youtube, the right only sounds like it has either a bad connection, or the cone has become detached from the housing. Tried all the fixes on the software and setup end, but no change. The only reason I got this laptop was because I am a stock holder, and wanted to support the company. Now I'm just angry that this seems to be a very wide spread problem that Apple is not taking care of. I am very very disappointed with them. Maybe a class action lawsuit will get their attention.
