Many Sound Effects not playing (Audio Bug)

So yeah, I have a problem with my game. Many sound effects in New Genesis simply aren't playing at all. Most Techniques, many enemy attacks, and other seemingly random actions don't have any sound at all.

I looked through the ingame settings, but there's hardly anything there for sounds; none of them changed anything. I tried reinstalling the game completely. I tried running the tweaker and troubleshooting+checking for missing files. Nothing fixed the problem.

I don't know what else to do. Does anyone have any ideas on how to fix this issue?? (I play on the Steam version btw)

EDIT: I realized what seems to be causing the issue. The sound channels in NGS seem to be all messed up. Also the game wants to play audio in surround sound even if you have it disabled in the ingame settings.

I was able to workaround this by enabling "Spatial Sound" setting in my Speakers properties in Windows 10. Another possible workaround for now could be to use a pair of headphones with Virtual Surround Sound.

Hi. I'm having thee same issue with PSO2 NGS. So you had Spatial Sound enabled in Windows, and enabled as well in the in-game settings?
