I want to change the output to i2s out. The following are my modifications: Here is my prj.conf. Here is my app.overlay.

The signal looks ok, but the i2s-speaker does not output any sounds? Maybe the data and clk signal have been switched? or the speaker does not have enough supply voltage?</p><div style="clear:both;"></div>
