Mic Doesn't Work at all On App and can only hear 1 person talk on website

Basically, what the title says. Ever since I upgrade to a new PC, Discord's voice chat hasn't worked. I can't use the app at all to talk, and on the desktop version, I can only hear one person at a time now. I tried messing with my input/output settings, reverting to defaults, and checking permissions, but either I missed something, or Discord is broken for me. I'm wondering if NVIDIA HD audio has something to do with the issues, but I'm stumped. Any help would be much appreciated.

Details (just in case):

Windows 11, Intel Core Ultra 7, Z890 AYW Gaming WIFI W, NVIDIA RTX 5080, Sennheiser GSP 670 Headphones

Update:

I went into my Windows settings and disabled the NVIDIA audio for my TV/monitor, and that seemed to fix the hearing only one person at a time issue.
