White Noise using optical audio/toslink

When attempting to play the game using optical audio to a soundbar it often results in the game producing very loud white noise/static. Sometimes it will sound normal for a few minutes but then a certain sound will set it off, a spell cast, or sometimes music playing then it just persists as white noise until restarted, with the white noise sometimes coming back immediately upon restart, and sometimes it being fine again for a little while.

Other things that may be playing at the same time (youtube/music/etc.) continue to play as normal but are drowned out by very loud white noise from V Rising.

The game can be quit and sound immediately goes back to normal. Disabling sfx/music in V Rising also stops the noise from occurring. Tested with several other games and the only one exhibiting this is V Rising.

Have tried resetting game settings, deleting the stunlock out of appdata, uninstalling/reinstalling via Steam as well, but the issue itself persists.
