Imx93 debugging hdmi audio

[xiang_1001]

bsp version: imx-6.6.36-2.1.0.xml

There is a sound card node now, but there is an error when using the command to play. How to change it?

you can refer to the spdif define in the frdm dts file as below

In the link above, there are only a few about spdif configuration. I have the same configuration as it, but the hdmi audio is still not available. Would you please take a look at it?

[xiang_1001]

There is no difference between the linked dts and the one I configured.

sorry for my late response, local team is on holiday from 10/1-10/8, I'm limited to access the mail,  I attach the dts files which are tested by the internal team and work with hdmi audio, you can refer to that, if still failed and you are urgent, you can "submit a ticket" from the link as below, attached your error message and dts files, my other location engineers would continue helping you

Hdmi audio still doesn't work.
I would like to ask, has nxp tried hdmi audio?
This lt9611 driver can be used on imx8, and it also has audio. However, on imx93, no audio came out, and an error was reported below.
