Speaker issues? Yep. My MBPtb 2017 was just fine until installing Mojave. Immediately after that the right speaker distorts all the time. Sounds like garbage. Left speaker is fine. Audio output to external speakers is fine. I worked with Apple techs to do all kinds of resets and trashing prefs and it didn't solve the problem. My company's tech support says to wait for the 10.14.1 update and see what happens. Anyone else have that happen?
