Hi

I create a topic 1 week ago, but it seems that nobody keeps eyes on it.

https://devtalk.nvidia.com/default/topic/1058456/jetson-nano/how-can-i-debug-by-using-mc-err-error-information-/post/5369659/#5369659

I just wonder whether the question below in the Topic:

I found the system’s own sound card driver named ADMAIF1 can play audio and output I2S data.

I tried to replace the codec part of this driver dai-link from xbar to wm8960, and then replaced the routing content you shared in the link(https://devtalk.nvidia.com/default/topic/1052068/jetson-nano/nano-compatible-i2s-soundcard/post/5344933/#5344933)

the driver after modified can be successfully registered to the system,

but it will not output I2S data when playing an audio file, can you provide some ideas?

or just tell me that is this feasible?

thanks.

downey.
