I recently installed a phat dac on a pi zero. When i play the sample sound, the first few seconds the sound comes fine and then there is severe crackling noises. Same with either airplay or raspotify. Can someone help? I am running raspbian buster

dumb question maybe, but have you tried another speaker, it’s likely not the issue ,sounds a bit more serious, I have had mine hooked to many different speaker without any issues …
