Hi,

Thank you for your interest in NXP Semiconductor products,

I'm reviewing your dts, if WM codec isn't in your board you could remove it,

Regards

Hi MJD,

I can see already 2 mistakes in the devicetree you shared, 2 devices are trying to use the same SAI(sai3), and your audio sound card doesn't indicate what codec you want to use.

Also, you have to decide which device is the master, SAI or codec, and configure your GPIO depending on that, see more information in the iMX8 user guide PDF.

We are not able listen music, but some buss sound we can listen.

Guide me if in any changes required are any necessary things to check.

Hi,

Thank you for your inputs, I've seen that there is no error detected in the digital interface, therefore, there probably aren't errors on your current setup.

I'd look in the analog side, there might be the issue, the error message that you saw is prompted when the play is interrupted, therefore the communication is ok, now look into the analog side,

Sorry for the delay,

Regards,
