Heh, usb-c the connector is used for many protocols only a few of which are actually USB (pci-e /thunderbolt, DisplayPort, i2c, etc). The analog dongle is one of these. There is no usb involved, just using the pins of the connector for analog audio. Dongles with a DAC are actually a usb sound card, and are usable even on desktop computers or using usb-c to usb A converters.
