Was going through a PRO I/O module, learning it's in's and out's so that I can train the rest of my team here at Keslow Camera on it's functionality and what to expect. Currently running it on a Scarlet. Using firmware 3.3.4 (beta). I have seen in the .txt file 3.3.3 the following...

"* Added Pro IO Support (Video, Audio, Timecode, Sync, Genlock, GPIO and PWR)"
"* Added Audio Playback"
"* Added Pro IO HD-SDI audio on PREVIEW and PLAYBACK"

Am I correct to assume that play back currently is just for channels 1 & 2 still? I can see the levels on all 4 channels moving, but I can only monitor channel 1&2 through HD-SDI during playback and during preview.

Headsets work for monitoring all 4 channels in playback and preview.

And Exporting a clip with audio, I had to check all "external audio" for audio to be attached to the clip, not just all "Camera Audio".... is this normal?

Thanks for any thoughts.
