Thanks for your reply, John!
I’m sorry for not being clearer. I don’t want to record into a mic. I mentioned the mic because it indicated to me something was different about these audio channels than the rest. I want these tracks to be the same as all the other tracks. At present, I can’t actually put any audio at all on these tracks. If I bring a clip in, it puts channel 1 on track 3 and channel 2 on track 7. Premiere won’t let me put anything on 4, 5 and 6 despite the fact that they’re enabled.
Any idea why these tracks would look different than the others and behave this way?
