My Miniamp works flawlessly on a Pi4, but not on a Pi3 with the exact same setup:
- Raspbian Buster Lite
- Fresh install
- Nothing on the Gpios except the Miniamp
- Added dtoverlay=hifiberry-dac to config.txt and removed the standard audio there
--> speaker-test -c 2 works on Pi4. On Pi3, the test is seemingly running, but no sound is played.
aplay -l also lists the Miniamp correctly on both Pis.
What could be the reason for the Miniamp to not work on that Pi3?
