I tried 2 setups, no difference:
1 piZero W with miniboss DAC
2 piB+ with Hifiberry DAC+ ADC PRO
In both situations, silence in audio track is dead silent, but when I stop Moode playback , and after a few seconds, the SMSL amp start a low volume buzz.
Is there a setting I overlooked that can stop it? Ideally I keep the SMSL amp on all the time.
Perhaps playing a silent track loop whenever audio stops?
If I leave the amp powered on and disconnect the rca cables, it goes dead silent. I also tried an audio isolator between DAC and AMP, that had no effect.
Edit: Solved - Not 100% sure but I removed a ground loop isolator and problem is gone.
