Sound issues pi4

I’m new to Volumio and its OS. Was trying to get audio out of headphone jack of raspberry pi4 without sucess. I’ve been researching for 4 day now and have tried a lot of “sudo amixer” lines and nada! I know the preferred method is a DAC, however Im new to electronics an will appreciate your help!

did you set it in volumio? no need for sudo amixer

Yes, sir! that was before all the other troubleshooting!

The issue is with the pi4, Sound comes out in pi3. Any suggestions to get audio on the pi4 out of headphones jack?

Update! It is not the raspberry pi. I am using a “raspad”. I just have to figure our which dac plug in works.
