Supporting analog audio out over USB-C is definitely something that varies from device to device. Some adapters are passive requiring the device to send analog signals or some devices can be active in which they have their own DAC and expect a digital signal. Some devices will have their own DAC on board and can support a passive device, some devices do not have one and will require an active adapter.

Generally speaking, you'll probably have more success with active (DAC-based) USB-C to 3.5mm adapters.
