DA7218 DAI Output

I am testing the DA7218 reference board with great success. The audio input and tone generator are both working well, at least from the input to the headphone output. However, I am unable to get any data out of the I2S port. I have configured this port in I2S and TDM, but the Data-out never toggles. The register setting file is attached. No doubt it's something very simple that I have set wrong. Any guidance would be appreciated.

Thanks-

Mike Schell

I discovered the solution.

I discovered the solution. Set the dai_oe bit in the DAI_TDM_CTRL register. This bit controls both the TDM and I2S modes.
