I2S output with CS4344

Sorry to dig up such an old thread, but there's another reason for the CS4344 not to work.

The CJMCU-4344 modules for sale on ebay etc. have a PCB error where the power trace isn't connected. The result is a garbled hum instead of audio.

I used the CS4344 datasheet and a multimeter to find a convenient place to solder a jumper wire to, and "Bingo!". It now works like a charm.
