Same problem here. Opening up the waveform view does seem to solve the problem, at least for RAM previews. Haven't checked if this is an issue with renders as well.

I'm experiencing the same audio issue with rendered output.  No issue with RAM Preview.  Solely rendered output.

Attempting different audio output settings and the problem is worse.

Well, I think I have solved my Ram preview sync problem. I converted the

aif audio file to wav and haven't had an issue for about an hour.

Todd,

As someone who's lost *many* hours trying to sort this, as a "known issue" that you're working on a fix for, perhaps it would be worth stating that here:

Premiere Pro CS5 known issues

http://kb2.adobe.com/cps/840/cpsid_84021.html

That's where I checked first- nothing. Still nothing now. I figured it would be a list of the known issues, seeing as it's called "known issues". From what you're stating, this audio problem is a known issue.

And if I seem like I'm being overly repetitive, then you've obviously never dealt with *posting* a support request to Adobe. It goes like this:

Me: "I believe this software has a bug. Here is a clear explanation of why, and under what circumstances. I'm on a Mac, and here's a file I've uploaded for you to replicate it."

Adobe: "Here is how to uninstall and reinstall CS5 under Windows."

Me: "Mac. File. Replicate."

Adobe: "Please run setup.exe".

Me: "Mac. File. Replicate."

Adobe: "Please upload a file so we can test it".

Me: "Sigh. Mac. File. Replicate."

(Repeat last 2 steps multiple times until technician calls and you can force it to be escalated to someone who reads.)

Sheesh.

Hi Todd,

Thanks for updating it- perhaps that will save someone else many wasted hours.

You noted: "that document of known issues is a bit of a problem in that people (including some here) think that it's comprehensive."

Perhaps it would be more obvious and we'd all stop stupidly assuming that the page on "known issues" listed the known issues if you named it something more accurate. For instance "Known issues that we can be bothered listing" or "An incomplete list of known issues- there's some we're working on a fix for but still would like you to keep stumbling over."

I did wonder how you could release software that can't play one of the most common Mac audio formats in sync. Was sync considered overrated during testing? Did Adobe figure that it was an interesting style evolution?

On an interesting side note, I asked to get my 30 day Linda Video membership extended because I'd hardly been able to use it properly dealing with this. You can imagine how long I wasted explaining the situation to Adobe tech support, with them telling me "We can't, because the problem you're describing isn't a known issue- it must be a problem with what you're doing."

Sigh.

I had the same problem. The 10.0.1 update DID NOT fix the problem for me. What did, was closing the audio panel.

I've had some issues with Audio during ram preview as well. This seemed to have fixed the issue, I'm using a Mac so not sure if it applies to all setups..

Preferences > Previews: UP the Audio Preview Duration to the length of your main comp.

Preferences > Audio Hardware: Increase the Buffer Size (max if possible)

I read in your initial post that you also have mp3 audio in this project.  It should be converted to aiff or wav as well.  For as long as I can remember, Compressed audio files have given AE absolute fits and they should be converted to uncompressed files.
