I don't think what you're asking for exists, as neither standard was really designed to do that. DP does not have audio input capability at all. The closest thing is probably the ARC (Audio Return Channel) feature of HDMI; but this is not designed to route a mic input back to the PC. Rather, its intent is to provide a way for a TV with a built-in tuner to use the HDMI port to digitally send audio from its tuner to an A/V receiver. I would be very surprised if any consumer video cards have the ability to decode the ARC; and good luck figuring out a way to get an ARC-compatible signal from your mic or headset.
The latest version of the DP spec supposedly allows USB data to be routed over the video cable, which would theoretically allow you to use a USB mic. But like ARC, I'm not aware of any video cards that implement this functionality.
If you really need the return audio channel, I think you're just going to have to run some good shielded low-loss audio cable alongside the video cable. Or use a USB mic over the same cable you're using for mouse & keyboard.
