Starting a Quicktime Audio recording with Catalina Dev Beta 5 on 2018 or later Macbook Pros outputs files with no sound (Macbook Pro Microhone selected). Example file here: https://www.dropbox.com/s/ib67k0vg8cm93fn/test_no_audio%20%281%29.aifc?dl=0
During the recording recording Console shows this error:
"CMIO_Unit_Converter_Audio.cpp:590:RebuildAudioConverter AudioConverterSetProperty() failed (1886547824)"
We have an application that records the screen and audio at the same time using AVFoundation and the resulting video files also do not have audio. However when inspecting the CMSampleBuffers, they seem fine: https://gist.github.com/paulius005/faef6d6250323b7d3386a9a70c08f70b
Is anyone else experiencing this issue or possibly have more visibility if it's something Apple is working on?
Anything else that I should be looking at to tackle the issue?
