Hello Danelll,
Thank you for responding.
I understand that RT5640 changes need only the device tree changes. However, in our design, we used a different audio codec (TLV320AIC3204 from TI) instead of the RT5640. I would appreciate it if you could let me know what changes are required to enable TLV320AIC3204 codec with the Orin Platform.
I have gone through this wiki Audio Setup and Development — Jetson Linux Developer Guide documentation
and made necessary changes.
