Hi
I seem to have an issue where, unless the preview is stared form the beginning, the audio track is offset by about 10 seconds (starts about 10 seconds into the song). This is a real pain when you want to edit a specific piece and you must preview the WHOLE film just to check if it is right. Odd thing is though, this only occurs on one of my videos while the others are perfectly fine.

If someone could explain this and (possibly) give a solution that would be great.

EDIT: I just found that the music is playing at the correct point when started from the beginning and ends where it is cropped (don't understand why it has been cropped since I have not done so) but when started from another point the music starts later but continues past the cropped point.

I have that same problem, I can't figure out what to do.
I'm trying to do lip syncing put it's really hard when the audio is suddenly 5-10 seconds ahead of the time...The only way is to watch all the way from the start to actually hear that audio is in the right place.

A couple things to try:

Lower the preview resolution. In my experience, the less PD has to do while previewing, the more likely it is to keep things in sync.

When out of sync, press the spacebar twice (try waiting different intervals from "tap-tap" to "tap... tap" where you wait a second.) This stops/restarts the preview, and allows PD to re-start at the current point with audio & video.

Sometimes I've had it do better when the preview window is smaller. (I'm guessing similar to lower res.)

PD is juggling lots of data/files during preview mode. Depending on the hardware, source files, resolution it can struggle keeping up. I think it prioritizes keeping the video moving... audio is secondary.

Anti-virus software can slow things down, low memory can slow things down, lots of background apps can be an issue.

Different formats for audio work better than others. wma works well for me, but some formats are tougher on PD in preview mode.

Finally: Just for fun - When I'm doing a serious session, I reboot my machine just before editing. I want PD to have max resources because my machine was great when purchased, but now is maybe middle of the road (with a tailwind...) but realistically it's on the older, underpowered side.

Hope some of this helps.
