Not sure if this is a codec configuration issue, have you check with codec vendor?

Hi,
It seems you don’t enable the capture path set on the Tegra side.

" The first two commands are executed before play or record.
sudo amixer -c es8316tegra cset name=“I2S5 codec master mode” “cbs-cfs”
sudo amixer -c es8316tegra cset name=“I2S5 Mux” ADMAIF1"

Could you please add the below mixer control and test?
amixer -c es8316tegra cset name=“ADMAIF1 Mux” “I2S5”

If you still see an issue please share dmesg logs and capture trace log @

But There is no sound in playing the recorded audio, and it is normal to play the downloaded audio. ASDOUT have no signal when record.
