Sound exporting terribly

I have a project due to the client today, and have a major problem.
The sound it’s exporting is totally distorted from what’s in the TB file.
It sounds great in Animate Pro, but at least three of the sound layers are sounding echoey, missing, or like a buzzing sound every time I export.
This happened to me years ago, but I thought it was remedied since.
Please advise.

Don’t compress on export. By that I mean export the move at full audio quality.

Also, if f your originals were imported MP3 files, go back and use .WAV format instead. MP3’s use compression but WAV does not.

If you’re still having the same problem after following that advice, contact support to have a look at your project.

No project file, so cannot judge.

Or post some screenshots?
