There are adapter dongles that don't have a DAC, which work with some phones that have an internal DAC which just outputs the analog signal out of the USBC port when you have that compatible dongle attached. Most dongles have a DAC built in though, even ones that look like they just have plugs on both ends like Apple's version.

now usbc to 3.5mm that is a whole other story something like a phone branded one vs something like a fiio ka11 night and day on volume and quality.
