So I have the Hunterspider V3 gaming headset, and I plugged it into my new PC. At first, it worked fine, but now, the headphone jack on the rear of the PC, and on my monitor. The headset still works on the front port, and on my Nintendo Switch. If it helps any, these are my specs

CPU: Ryzen 5 2600x
GPU: 1070 Ti
RAM: 16 GB 2400 MHz
MOBO: MSI x470
SSD: 250 GB
HDD: 1 TB
PSU: 650W Gold+
Monitor: 34UC79G-B

Any help would be appreciated, thanks in advance.
