Is your DAC/AMP externally powered? With my Pico, anything I plugged in had noise issues. Tried a few USB powered DACs and DSP units.
It is externally powered, yes. Although I did go without it for a week with no noticeable issues.It's just a simple DIY PPA amp. Whatever the issue is hopefully the people affected are an outlier. What product in particular did you have?
