ProtoDAC TDA1387 X8 project

This type of non-regular glitch could be due to how the DAC chip reacts to the audio signal suddenly starting or stopping i.e. when MPD opens/closes the ALSA output.

Yes. If I ever get a tic (rarely), it is always after the last track, presumably when MPD closes the ALSA output.

Using a powerbank for the RPi and LiFePO4 battery supply for the Allo Kali/ProtoDAC. SBC Jumper on the Kali is off, so the supply is separate from the RPi.
