Hi, I’ve just set up a new Raspberry Pi 4 with the Pirate Audio Headphone Amp.
I’ve disabled the default audio in
/boot/config.txt, and can only see one device after
aplay -l etc…
I’ve enabled SPI and I2C
Iris launches, I can see the mp3 lists from the local directory, the buttons work, the mini display shows the playing track details (selected from the web interface locally and from my mac), but no sound.
I’ve tried different headphones.
Is there something simple I’ve missed?
I’ve read most / all the related posts although the fixes seemingly have been rolled into the git repository by now.
