2.806 No Sound, Pi 4

I feel I need to perform a factory reset to go back to previous version so that I can listen to music…

Performing a factory reset might help, you can try that to fix the issues in /boot/config.txt

Just adding my experience in case it helps others… I had a similar situation, I run a HDMI splitter that pulls the sound out of a HDMI cable and gives me a clean audio jack signal (not that messy sound the Pi normally gives) then into a 70s Sansui amp - I love the sound output, no need for a DAC here…

Anyway, I had no sound either, turns out I needed to tell Volumio I had a DAC (doesn’t matter which once, but Adafruit worked), then reboot, then change back to my original setup and reboot again…

All sorted now and Volumio lives again in my backyard bar :slight_smile:
