I trying to use the PmodI2S for the first time, but am unable to get sound from the port.
I read thru the post "Pmodi2s Stereo Output Pmod - How Can I Get This Thing To Work?", but unfortunately it didn't solve my issue.
I'm sending I2S audio to the pmodI2S module with a PIC32. The PIC32 is toggling the MCLK pin at 8.3 MHz (I've also tried 11 MHz). Here are the frequencies on the pins, verified with a scope:
- MCLK (pin 1): 8.3 MHz (Supplied by PIC32)
- LRCK (pin 2): ~31.45 kHz (2x channels)
- SCK (pin 3): 2 MHz (I've tried it with the PIC32 supplying this and without supplying it, i.e. internal. When relying on internal, it outputs nothing.)

- SDIN (pin 4): 16-bit data, 32-bits per channel (2x channels) = 64-bit frames
- GND (pin 5): GND
- VCC (pin 6): 3.3v
I'm using Apple headphones that came with my phone to connect to the output jack.
Been fighting this one for many several hours. Any help will the greatly appreciated.
Thanks
