I am using an R50 as a webcam via the direct USB-C connection. Can I use the built-in mic for this? The levels are being displayed on the flip screen, so I know that it is working. But no sound is being transmitted via the USB, because neither OBS nor the built-in Windows Camera app are registering any sound.
I suppose another way of looking at this is simply to ask if the USB-C connection passes through audio, or is it only video?

No. The USB-C connection uses the UVC (USB Video Class) protocol, which only allows the transmission of video over the USB cable. You need to use a microphone connected to your computer for live audio.

Thank you. I really appreciate the fast response - you saved me from a lot more time spent tinkering. I will mark this as solved.
I'm still a little confused. The Canon USA website shows that the camera supports UVC and UAC. I believe your answer is correct, but that is confusing.
I think this would also answer a couple of other threads from people asking about using external microphones, since that audio would still have to go through the USB connection and it cannot.
