I am trying to setup a Squeezebox System using a Raspberry Pi 3 B. I recently bought a SMSL AD18 Amplifier with integrated USB-Interface. The USB-Interface is recognized by Volumio and the sound is playing through my amplifier.
But I have a big problem. When restarting the Raspberry, I get a horrible distorted noise out of my amplifier while the system is booting. I’m glad, I turned the volume down before the first trial because otherwise I might have destroyed my speakers.
I have tried different platforms, all show a similar effect:
When starting Volumio the noise starts a few seconds after I power on the Raspberry. It lasts about 7 seconds and stops right at the moment, when the Volumio Screen appears on the HDMI-out.
With PiCrePlayer the noise lasts about 5 seconds, with mx2play it’s only about 1 second.
Do you have any suggestions? Many thanks in advance.
