This is Joseph. So I've been having this really, really weird audio problem with my mac book air's internal microphone. If I record something in, say, quick time or something of the sort, my voice doesn't seem to get picked up, even though my volume level is set at 50% or so. However, when I invoke Siri or dictation, my voice registers just fine, or seems to. Furthermore, if I want to recording something, I have to go into system preferences>accessibility>dictation>enable the dictation keyword phrase and check the box. Then, and only then, will my internal mic work for all applications that use it.
I'm wondering what's going on here, and if any of you smarter mac users can possibly give me some advice as to what might be happening and if there's a fix for it.
