HDMI from PC to projector: Want audio coming out of projector NOT PC speakers

[Mason Methot]

So when I hook up my pc to the projector via HDMI, the audio comes out of my PC speakers instead of the projector (when we hook a speaker up to it). This is from what I remember.
We are having a movie night outside, got the projector set up. Have the HDMI running to it. I want to know how I can have the audio playing from the speaker hooked up the projector instead of the PC speakers.
Do I have to unplug my PC ones or change something in the PC sound settings?
I need to know quick, but Thanks in advanced!

Go to "playback devices"(right click the speaker icon near the clock), right click your projector in the list(it should be connected via HDMI) and click "set as default device"

Thank you, I'll try that in a bit!
