Soldered in pcm5102, testing it with external i2s source for now, just to verify setup and soldering. Started to work after 2nd attempt. Comparing to known working module (yellow one)

(Sorry for picture quality, i only posses DS0138 toy oscilloscope)

10khz on yellow module (known good)

10khz on my pcb

20khz on yellow module (known good)

20khz on my pcb

Looks very similar, relatively clean (oscilloscope is strugling here, actual waveform is really clean).

Next on setting up Onion and I2S.
