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 like its hollow 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

sorry but its not working either.

I figured it out, I did windows key + r and did %appdata% and i went to the folder called Fxsound LLC and it shows all the version that you downloaded in the past, which helped me find the Fxsound version that the volume options and save button works hope this helps.
