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?

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.
