Audio sounds different with current version

I don’t know if its because of the version update that Fxsound did but the audio isn’t sounding correctly, it sounds like the default audio system that a pc has installed with and the version before sounded much better with the audio options, but with this new version it all sounds choppy I don’t know how to say it, I’ve also tried using other legacy versions but they’re not working either, also sometimes the audio raises then lowers when I’m watching a video.

check the mastering and turn the master audio down sum
