Sound issues

Hello There,
I just updated to the laster beta release on Sept 5th. Now Boinx is not showing any audio. I am using a built-in camera on a Macbook Pro and the built-in microphone, but it is not working. I attached a usb mic, select it, still no audio. Is there a setting that I need to adjust?

set up a new video source, set video to none, the audio to the audio capture device & then use the new source in a new placer layer.

Thank you so much, I tried that and it worked like a charm.
