It's really weird because all my other games have no problem with sound, but Valheim seems to have an issue with Sonic Sound Studio.

This answer got me really hopeful for a moment. Could you rephrase it? such as close sonic sound studio? Like using task manager force it to shut down?

You could use task manager. For me, it was in the "hidden icons" on the bottom right window tray. i right clicked the icon and clicked "exit" or "quit" or whatever. Then, make sure to restart your game.
(it won't work if you do it while you're in the game still).

hope this helps
