Hi
Is this still an issue, apologies for delay. The attached wave file seems to be mono channels. Could you give a try with 48KHz, 2ch, 16bps?.
The problem still exists. I’ll try switching to a different WAV file

Did you followed the codec set sysclk function as per Audio Setup and Development — NVIDIA Jetson Linux Developer Guide 1 documentation . The error in your log indicates this could be one of the reason.
Yes, there is no modification to sysclk. Please help confirm whether the driver code is correct

I see a minor issue with your change, please update as per the attached patch
es8316.txt (1.3 KB)
Also mclk-fs = <256>; in sound {} node is not necessary as codec driver would control the MCLK as we providing it from codec dt node
Even after making the modifications according to your suggestions, it still doesn’t work
When playing audio, there is no error reported, it immediately returns, and the playback is not maintained
root@hzx-desktop:/home/hzx# aplay -D hw:APE,0 test.wav
Sorry, the issue with the “quit immediately” is related to the wav file. It can be played, but there is no sound

Could you probe I2S DOUT signal to check if we have valid data coming out?. If so, we might need to check the codec mixer control config like mute/volume etc..
I2S DOUT should have a signal
When starting or stopping the broadcast, there is a slight electrical humming sound
After updating the es8316 driver, sound is now playing, but there is a significant background noise resembling snowflakes. By executing the command to play the mono file “train.wav” followed by the stereo file, and then playing both mono and stereo files afterwards, the sound is normal. What additional configuration might be needed?
The first time there was snowflake effect, after playing mono audio, the audio with snowflake effect played normally. The register values for the two audio plays were the same.

Could you please take a look? Thank you
