Slow Audio Playback During RAM Preview

[Michael Szalapski]

That is weird.
Try transcoding them to WAV.

Very weird. I tried converting to WAV, but to no avail.

It turns out that what worked yesterday is changing my Audio Hardware and Audio Output Mapping in my Preferences to “Built-In Input/Built-In Output”. That seemed to fix the problem, although half way through the day, the problem returned. When I went back into my Preferences to change it, I saw that it had somehow changed to “Built-In Output” and the “Built-In Input/Built-In Output” option had disappeared!!

After a few hours of grumbling I went back into my Preferences, saw that the “Built-In Input/Built-In Output” option had reappeared!!!!

I changed it to that and the problem seems to be fixed for now. I hope it lasts.

I’m going to do some fiddling around next week and may repost if I find out anything.

Thanks for your help Walter!

@Pravin – – I feel your pain. I’m currently experiencing the EXACT same thing. Running CS6. One slight variation in the symptoms, is that after changing my system preferences to “System Default Input/Output”, it automatically switches back to “Built-in Output” when I go back to check on it. Bizzarre. Anyone have any other ideas for fixes on this issue?

i guess you frame rate is not ‘full res’. set it back to 25/whtever fps you use.
hope it works.

Just had the same problem. I closed GarageBand and restarted After Effects for the win. Close any audio programs and try your RAM preview again. You may need to restart AE. I tried everything but nothing worked except this. Hope this helps!

I have been experiencing the same thing tonight. Bought I still had Logic PRO running in the background. Once shut that done and went back to AE, the first playing of the RAM Preview played fast. Then the rest have been correct. So I believe you are right about another program accessing the audio processor. Once AE is the sole controller the audio plays fine.

Thanks to Creative Cow and all of you who contribute here. Without this thread I’m sure I would be pulling what’s left of my hair out in the next hour or so.

SUCCESS!!! I was experiencing the same problem, and I got it resolved, I watched a youtube video of a guy saying that you needed to match your Frame Rate in the composition settings to your RAM preview’s frame rate, but that didn’t work. what worked like a charm was, I had garage band open still, I closed that and the problem got fixed right away! HA! who would have thought! thanks
