How to use eARC with a computer

[PortalKeeper]

Is it possible to transmit sound from a TV eARC port to a USB port on a computer without an HDMI audio extractor? If so, how?

Technically yes, but no devices with these features exist.

Isn't there an easier way to get audio out of your tv?

Yeah but I want to use a particular audio interface that only has one USB-C port and that needs Windows or Mac to run (I have Windows).
