Hi there,
I'm pretty new to the world of Pi. I have already quite successfully set up a Pi 3 with an external USB DAC to be used as a home theatre system and Airplay device (shairport-sync is great), so I ventured in to the depths of multiroom audio.
Got myself a nifty little Pi zero and a pHAT DAC. My first time soldering and it all seems good.
BUT - I'm experiencing some issues with noisy output. Whenever there appears to be a high CPU load or a heavy SD card load my headphone jack outputs A LOT of data transfer noise. It can be so intense that if I am listening to music while shelled in to the Zero, the music can cut off completely.
Is this a known issue, or a potential soldering problem, or a software issue?
Any help would be greatly appreciated. All firmware is totally up to date, and the only thing I have plugged in is the official Pi USB Dongle, and I'm using the official power supply.
