High frequency noise in all our audio files

Hi.

Suddenly our audio files have a static high frequency noise / stuttering in them. Both when playing them inside the content browser and in game. It’s extra audible on our ambix files where the noise is really loud. On some of our mono files I can’t hear it at all. Don’t know if they’re not affected or if the noise is just very low on these files.
This just started to happen, before all our sound files sounded good.

I have tried to reimport the sound files and I have also tried to add complete new files but all of the audio files suffers from the same issue.

This seems to be more related to our project than to the engine itself. I created a new project from the third person template with the same engine, and then imported the same files and they all sound good.

It also seems to be Windows related since quick launching to console devkits or building a console package seems to work fine. But when packaging for windows the audio issue remains.

We are on UE 5.3.2 with Hazelights Angelscript support.

Any help or pointers that could be provided to me in this matter would be really appreciated.

Best regards,
\Ola
