I'm doing a DAC using U8 in a 2ioxsd configuration. I'm not using the i2c with the DAC chip I intend to use. I have my own hardware without the CS4392 but it fails doing audio playback. To track down the difference between my hardware and the Eval kit I removed the CS4392 from the Eval Kit and this now fail in exactly the same way as my own hardware. So I need to disable the i2c in the project. How do I do this?
Best regards,
Thomas

Hi,
Can you specify more information on the issue such as the software package, evaluation kit that you are referring to?

In order to bypass the I2C based codec calls, remove the instances where the codec configuration related calls are made:
- from audiohe.xc, remove the i2c related calls
- remove the i2c calls from the startup and stream configuration
- remove the port assignments from the main.xc
