Adobe Premier sounds terrible after it crashed!!

Hi  Folks,

I'm relatively new to Premier Pro, so maybe this is an easy fix that I just don't know about?  I've tried a ton of fixes and nothing is helping! Here's what happened:

I was minding my own business, working in Premier Pro....la la la. I was adding a video transition to my sequence in the Timeline and Premier crashed. I got a screen note that said it crashed and they'd try to restore the file but that I should save it with a different name, so I did.

When I opened up the file again to continue working, the audio sounded TERRIBLE! It was really loud, scratchy, poppy, and uneven. It did not sound like the smooth audio that I had just listened to minutes prior.

I tried so many things:

I renamed the file again.

I closed Premier and re opened.

I quit CC and re launched.

I shut down my computer and restarted.

I cleaned the media cache.

I do not know what else to do?? Can someone please help? I'm on deadline and I cannot deliver files that sound like crap!

Thank you!
