I've seen this kind of addressed in other posts, but usually in reference to older versions, and haven't yet found a solution.
Basically, I sometimes end up with a comp that delays start of the RAM preview by up to 20 seconds (and then it plays just fine). I found a (half) solution online which was to mute all audio for the comp, and then it plays instantly without a hitch. That's not really a full solution for me, though, because often the point of the RAM preview is to watch with audio. A few seconds I could live with, but 20 seconds every time I wanna check my work is just too much.
As I said, it only happens sometimes, so I suppose there could be something wrong with the audio file, but it happens often enough that it would be a coincidence to have so many similarly corrupted audio files.
Thanks for any help!

What format are your audio files?
Also, you might consider updating AE. The latest version is 13.7.x
These are AVCHD MTS files, the audio is 48K compressed (Premiere doesn't say more than that).
I definitely will update, thanks!
