Working with a scarlet running scratch audio into a cam via shotgun mic. Set up audio yesterday. Saw levels, recorded sound. Today, turned the camera on, no sound. Got a green bar of hiss when we listened with headphones. Messed with it for a while until we had to start shooting.

On an epic shoot last week we were setting up the cam with scratch audio and it took about 20 minutes of going through the menus, rebooting, menus etc etc before the sound suddenly started to work with seemingly no clear reason.

Anyone else experience this? Am I doing something wrong?
