Premiere making audio file sound like robot, sounds fine on other platforms

[Morvi]

Hi

Just as the title says, I have a voice over audio file. When I play it in Itunes, Quicktime player, a random voice memo app and in preview it sounds perfectly fine. Its not until I bring it into premiere pro all of a sudden it sounds compressed, fuzzy and robotic. Its as if I have the mic inside my mouth. None of this distortian is on the original file and makes it unuseable.

The audio file is a .m4a file and I am running on a 2019 Imac. This has only happened within the last 2 weeks. Previously it has been perfectly fine.

Ive tried 

deleting cache

deleting and reinstalling

using older versions

any help is greatly appreciated.

Make sure the Default input in the Audio Hardware is set to none (or build in).

yep have tried that but doesn't help 😞

convert the file to something uncompressed like 48k 16bit aiff...    and if this file worked previously on this system, I'm guessing you did some sort of update...  these things usually don't happen on there own (I did say usually).

Any solving? I am experiencing the same thing.

Had the same thing, when I went into the file, I saw it had multiple audio channels and I muted all but one, was perfect.
