Troubleshooting
No sound output
Check all cable connections, verify that the AMP2 is properly seated on the Raspberry Pi, and confirm that the audio output is correctly configured in your OS.
Distorted sound
Ensure that the input signal is not clipping. Lower the volume levels, and check speaker connections and ensure the correct speaker impedance is matched.
AMP2 not powering on
Double-check the power supply connection and ensure it is providing the correct voltage. Try a different power supply.
Humming or buzzing noise
Check for ground loops and consider using a ground loop isolator. Verify that all cables are properly shielded.
