There were no results for I'm new to Adobe, I've been an Avid editor for years and just switched from Avid MC6 to Premiere cs6. I'm on a MacPro with 16 gigs of ram and NVIDIA Quardro 4000. For some reason when I load an AVCHD file, the pic plays fine but no audio. If I scrub it for about 10 min. it starts playing sound. Can't figure this out.
I'm not brilliant at this but if, as you scrub for your 10 mins, you see a yellow progress bar working away in the bottom right hand of the screen that means Premiere is conforming/creating 'peak' files etc. From experience I don't touch anything while this is going on and even on long clips (measured in an hour plus in my case) it doesn't take long. After that the sound works fine, for me. It could be this you're up against.
