I recently installed an AudioIQ DAC+ device on my RPi3b+ running buster.
Following the directions in the user guide, I was able to get to the point that the drivers are loaded and appear to run, but no sound is emitted.
I'm wondering if I need to do something to force analog output to the headphone out port that isn't covered in the manual?
Here are some useless details. I would have put in also what's in alsamixer, but that doesn't translate well here.
What else should I check?

Update: Using the test image works and proves the hardware at least is not broken.
