Hello! Just curious if AVAssetWriter append() randomly fails for anyone but me? Seems to happen when live streaming (encoding with VTCompressionSession) and recording (with AVAssetWriter) at the same time.

Hello! I've two mics connected to a USB-hub. The USB-hub is then connected to my iPad. Both mics are part of the audio session's list of available inputs. The problem is that regardless of which mic I select in my app (using setPreferredInput() on the audio session), the audio keeps coming from the mic that was last connected to the USB-hub. Anyone that knows if this is a limitation in iPadOS/iOS?
