Audio dropping out - It's actually more than a bug, it's a design flaw
After reading all of these posts, and having had the same issue, which now I can solve, and re-create as will by simply separating the project files from the media drive, I have an faily good idea about the cause. There is a flaw in the software design regarding how it interleaves the audio with the video files. It gives a log of priority to running the video without interruption. This causes an audio buffer underrun. This is why it will play audio longer before dropping out after you increace the buffer size. Still, there is no buffer large enough to hold all of hte audio your timelines need to play.
Yes, this is bug in the program. It's actually more than a bug, it's a design flaw. There is too much code running between the time Premiere serves a frame of video, and it finds the audio for that frame. They way they designed the program to maintain sync, requires it to drop the audio lest it run behind the video.
This can be fixed, but it will require Adobe's software engineers to fix it. Seeing how many years have passed with no actions from Adobe, I wouldn't hold my breath. I would recommend switching to AVID. Adobe either does not care to fix it, or does not know how.
