What kind of device are you trying to use this with? Are you trying to have audio out or audio in?

Several device don't support analog audio through USB-C, called audio accessory mode (google pixel being a common one). In that case you need a headphone with a DAC.

Your only other option would be to use a hub. Something like this. But even using that, it's hard to know for sure if it would work or not since it's dependent on the design of the specific device you are using.
