Question No audio from hdmi to monitor speakers

[PetarV]

I just built a pc. Its all fine except there's no audio from the monitor speakers. I've previously used the same gpu and monitor in a different sytem and they worked fine. I've tried reinstalling both the gpu and monitor drivers but that accomplishes nothing.
One thing to note is that I get sound from my headphones if they're connected to the pc through a usb dac(dragonfly black) but they dont work if I plug them directly to the port in the case. Running on win10. Any help is appreciated!

Did you set default sound device in Control panel > Sound ?
