I bought this adapter:

to connect my headset to my laptop via USB C. Unfortunately, nothing is happening there. Headset is in the 3.5mm connector and the USB C connector in the laptop. Or is the adapter intended for the other direction?
Not at all… USB on the PC is not just power or data for audio
For that have a 3.5mm jack
Ehmmm… No?
