Can't play audio with Raspberry Pi 5 using IQaudio DigiAMP+

[mackan92]

Hi!

I have been struggling getting it to work play audio with my Rasberry Pi 5 with IQaudio DigiAMP+ connected to it.

I have the following settings:

dtparam: "audio=off"
dtoverlays: "vc4-fkms-v3d", "iqaudio-dacplus", "unmute_amp"

It detects the audio card but I just can hear a little noise when a sound is supposed to play.

I have tried to play a test audio direct in the terminal using:

aplay /usr/share/sounds/alsa/Front_Center.wav

I don't get any errors, but all I can hear is a very minor noise if I put my ear close to the speaker.

I have tried the speaker by installing Raspberry Pi OS, and the speaker works just fine. I have checked if the correct PULSE_SINK is being used and it is.

Am I missing anything here?
