I tried the official pi power supply on just the pi/dac. About the same amount of noise as coming from the 30V supply thru the linear and buck. Definitely a power supply issue. I really want to stay with one power supply to keep it simple. I already am using most the outlets on two battery backups at work.
I only hear it when the player is stopped or paused. Not during a song or between songs. That’s why I wondered if there’s some code to mute the DAC when it’s not playing.
