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.
0 [HDA ]: tegra-hda - NVIDIA Jetson AGX Orin HDA
NVIDIA Jetson AGX Orin HDA at 0x3518000 irq 110
Can you clarify on the below points before suggesting right solution for your query
- Clarify on the exact I2S instance from AGX which was connected to external DSP?
- 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.
- Also attach kernel and flashing logs.
