I recently bought MacBook Air 13 inch (Model of December 2017). A friend called me to test the Handoff feature for calls, without muting the call. The stupid guy created an obvious feedback loop. Now at full volume, I hear a ringing sound. Have my speakers been damaged?
I learned online that swipe-sine wave test can be helpful
I'm on MacOS 10.13.4 Public Beta 7 (17E197a)
So I installed AudioTest, ToneGenerator, SiGen
I'm overwhelmed by the number of options I need to configure before playing any test sound
Am I in the right direction?
I just want to test the speakers for feedback loop damage
