Pi5 + Moonlight/Sunshine - No Audio coming through HDMI & case fan not working/always on.

Hi, I'm new to this so please explain to me like I'm five! Thanks. Edit: Audio topic was finally solved. 3rd party software was interfering with the routing of the sound to sunshine (Steelseries GG Sonar) my case fan (white one) is either always if using gpio as seen on the picture, or not at all, if connected on Gpio 17. (tried to do this: https://howchoo.com/pi/control-raspberry-pi-fan-temperature-python/) can you tell me what information you need from the terminal in very simple language because I really, have no idea what i am doing. Thank you so much!

Well, i tried a few things for a few hours now and i can't hear anything via tv. I'mma just go cry in a corner i guess

Use the fan connector on the Raspberry pi and let it regulate the fan see https://discord.com/channels/818384379197784084/1249037679769948241 for some details

Thanks for the reply. That's what I did for the fan on top of the cpu. But the case fan has a red and black cable. Might get it into the fan connector with enough force though (jk). Please see the picture attached. Case fan is the white box.
