Pimax 4k not recognized as audio device


Just got my Pimax 4K. Didn’t play with it much.
My first problem is that audio is only played in the PC speaker.
I tried to set audio as default on PIMAX P1, but it doesn’t appear in the audio playback devices.
Can anyon help? WHat should i see in windows device manager? Is my driver correctly installed?


Are your headphones plugged onto pimax? Can you list playback devices pleas


Yes, headphones are plugged.
I can see this
