I created MIP Driver with one microphone. Audio works in live, but when I try to play it in playback i don’t hear anything. I created rule for recording that microphone always. Also, I set that microphone as related to one camera.

As you can see at picture below, incoming audio (green line) is shown at timeline for selected camera related to my microphone, which should mean that record exist.

Also, I exported part of that audio using AudioExportSample, and got something but the sound is different.

If you use a virtual machine, sound is not working because it need to have a physical sound card if I remember correctly..

I am not using a virtual machine, but a PC with sound card. Also, I can hear sound in live but not in playback.
