Help with ripping the music from Vitamin Connection Switch

[Voosington298]

I've been trying to get the music for this game but been having some issues as all of the since after getting the games files they are all in a .vol format and I can't seem to open up these files to get the music files from which I know are there due to me checking the files through a hex editor. Any help would be appreciated. Thank you.
