I had some issue with a constant buzzing noise coming from my pc through the headphones. i remedied the issue with a couple of ground loop noise isolators but i was told that a simple dac could do the trick as well. I got one of those USB-C to 3.5mm with an internal DAC chip and because my pc doesnt have any USB-C i got an USB-A to USB-C adapter. problem is i dont get any audio. the pc doesnt even recognize an audio device being connected. looking online i couldnt find anything, the product page for the dac says that it should work though. i tried updating my drivers as well but as you can probably guess, it didnt help
