Le potat > adapter > headset

I have a headset that I’m trying to plug into an AML-s905x-cc. The headset uses type c display, so I got an adapter (male HDMI to female Type-C). It works on my desktop, but when I try to use it with the Potato, it doesn’t work. I thought it might be a display issue, so I grabbed another hdmi display, and the screen worked just fine with the potato. Is there some setting that makes the HDMI port not work unless it senses something (pull-up resistor or similar) to detect the screen side port? an and all help is welcome, thank you in advance!!
