I'm going to respond to my own post since the tech support didn't do anything, and if someone finds this post and are having the same problem then this post will at least be of some help.
The good news and the bad is that the problem kind of just went away by itself after a couple of weeks..
I don't know if there wasn't really anything in particular that I did that fixed it, but what you can do is try to disable hardware acceleration on discord or update your sound drivers.
When I asked about this issue in the novice network chat, it seemed like a somewhat common error for players and that it usually just goes away by itself.
