You have two problems (three if you count MP3’s).
-
Foobar2000 has a replay gain scanner system that can scan your files and add a replay gain tag to them which a music player can use to normalize the loudness.
-
Audacious allows you to open a folder and play all files inside and has replay gain support.

Most of those are updates to the flatpack base software not the actual display drivers.
It is unlikely to cause any issues updating them.
