Hey guys. I bought the apple usb c dongle recently. When i tried to use it, all i heard is just clicks and beeps once per second. The device showed up as "USB-C to 3.5mm Headphone Jack Adapter" under Settings>Bluetooth & devices>Devices>Other Devices, but i couldn't find it in Device Manager, so I can't even update its driver. My usb c port supports audio, so I'm probably missing the correct driver. How can I get it to work? Thanks

It's quite strange that they tell you it has to do with impedance, because the FiiO K5 Pro has a very low (2.2ohm) impedance output. It should work perfectly on paper.

Yeah, I'd be curious to know what source OP is using. There was a guy here recently with a Fiio K5 Pro, I think, that was frying his right side drivers. Coincidentally, my dad also has a K5 Pro and his Audio Technica right side driver gave out recently.
