bootcamp earphones constant high pitch sound regardless of sound level

I installed windows 10 and everything was running smoothly until a day later when my earphones suddenly started emitting a high pitch noise whenever any sound was played at a constant level. It is pretty much unusable unless I want tinnitus :( I'm not sure what the issue is, I’ve tried reinstalling the drivers but that hasn’t helped. I have cirrus logic cs8409 (ab 51) drivers and when I switch drivers to generic or endpoint, I get no audio.
