Jetson Orin I2S config

we use akm dsp on our custom boards, this dsp do not need control.
so, how to use i2s direct to dsp, without codec dai(use dummy)
i follow this ,Audio Setup and Development — Jetson Linux<br/>Developer Guide 34.1 documentation
but,there is no sound card create.

only has
0 [HDA ]: tegra-hda - NVIDIA Jetson AGX Orin HDA
NVIDIA Jetson AGX Orin HDA at 0x3518000 irq 110

Hi whn,
Can you clarify on the below points before suggesting right solution for your query

  1. Clarify on the exact I2S instance from AGX which was connected to external DSP?
  2. By default APE sound card would be registered on AGX, Did you made any changes to DT file of AGX?. Please attach the change if made.
  3. Also attach kernel and flashing logs.
