Try converting your audio to an uncompressed .aif or .wav prior to using it in AE. My guess is the decoding the mpeg streams might be screwing with your interactivity.

Do you have the most recent Wacom drivers? Also, do you have OpenGL disabled? How about the hardware accelerate panels preference? Disabled? Speaking of prefs, what are you using for your audio preferences?
Sorry for the delay in response, I was on vacation and have just gotten caught up enough to return to this issue.
I had the most recent Wacom drivers when reporting the issue. There was a new version released today and I have updated to that. Updating the wacom driver did not resolve the issue.
OpenGL is disabled. The issue persists with OpenGL enabled.
I disabled "hardware accelerate panels" and I am able to now scrub through a single audio track of any format on the second try.
- I attempt to scrub through a track and my machine beach balls for a minute
- I regain control of the program and am able to scrub through a single audio file
- When I get to a second audio file in the timeline my machine beachballs and After Effects stops responding just like before
Here is the most recent crash log - http://pastebin.com/cxBujE9F
This happens when switching from a wav to a wav, form a wav to an aif, wav to mp3, mp3 to wav, etc. It will freeze for a moment on the first file and completely hang on the second file.
As for audio preferences
Default Device: System Default
Buffer Size: 512
Audio Output Mapping:
Map output for: System Default
Left: Headphones 1
Right: Headphones 2
Audio Block Duration: 0:00:01:00
Maybe try increasing your Buffer Size. Try 2048 and see if the problem still exists. Aside from that, that's all I got.
I bumped the audio buffer up to 2MB (I am assuming it is in MB and not in GB) and while there are stutters every now and then I am able to scrub through both audio and video.
Thank you very much. I had increased the audio buffer before posting without success, so I believe it was a combination of the increased audio buffer and disabling the hardware acelerated panels.
