They don't support analogue audio signals - USB is a digital interface - you use a DAC to convert the digital audio signal to analogue.

USB-C absolutely supports analog audio signaling, it's called "Audio Accessory Mode" in the standard.

this is incorrect, look at the spec. I would not have commented something like that unless I verified it first
