[SOLVED] Pi Zero Glitches when SoX Resampling

[Niklasmagnus]

I would not blame the Pi Zero for this What kind of source do you use for up sampling?

Using a Pi Zero (w) with a PCM5122 DAC (PIFI) it does not have issues up to sources [16 bit, 44.1 kHz, Stereo]. Above it might not make sense (if up scaling makes sense at all is a different story).

The settings in Moode are for SoX: 32/384 with high quality.

The "top" command reveals <50% CPU for the mpd, which leaves still some headroom. I cannot hear glitches.

Without SoX diabled, mpd shows about 10% CPU

Meaning, before you invest in a Raspberry 4, you might want to check your setup.

The Pi Zero actually performs very well with Moode.

Are you able to stream Spotify and run 10 bands PEQ on the zero?
