[sdiy] Does usb c alternative mode allow analog signals on the multi-purpose pins?

[cheater cheater]

Thanks for the pointer to the spec. Appendix A talks about passive
audio adapters from USB C to headset TRRS. That includes both input
and output analog signals on the pins of a USB C port.

Glad that you linked me to the pdf, the last time I tried searching
for USB specs I found something completely different and it didn't
answer my question.
