Hi,
I'm having an issue where audio running into my computer via USB audio, isn't seeing or recording audio coming into channels 5, 6, 7/8, 9/10, 11/12.
Pretty sure it is the limitation of the Pro Tools Intro ie limited to 4 "Simultaneous recording inputs" as I had the same issue, even when i deleted channels 1-4 in the i/o I wasn't able to access 5 and upwards.
