problem with screen recording audio
I had a very important FaceTime call today that I needed to save to go back to later, so I screen recorded it. I triple checked that my microphone was on, and tested it before the call with another screen recording. However, after I recorded the call and went into my photos to watch it, there was no volume. This was a really important call and I am very disappointed in the audio not recording as it had earlier. Is there any way to get the audio back?
