Windows 10 update - Sound issue (bass blown out etc.)

I don't actually know if this is an issue with how WAV files are encoded now, or if it has something to do with a recent Windows update, but essentially my music sounds odd now, not like it sounded last month before I installed updates. The bass sounds like it's blowing out the rest of the track, especially at louder parts, and the track quiets down after the first few seconds.

Also - the track sounds totally normal in Ableton, which uses the same audio driver.

EDIT - Something else I've noticed with general music playback - it seems to bring up the overall level of quieter parts and dim the louder parts now. Has anyone else noticed a similar thing with a recent Windows update?

Fixed it (finally)! Turned out it was an issue with Dolby Audio being turned on, probably doing some loudness equalization as well.

For whatever reason, this latest version of Windows makes finding the sound device properties impossible to find.
