imx8mm sai1 can't open

[14766419]

HI:

I'm using i.mx8mm to develop audio, and I'm using SAI1. Why is this problem all the time?

root@okmx8mm:~# aplay -Dhw:1,0 /home/forlinx/audio/w1.wav
[ 72.078013] fsl-sai 30010000.sai: ASoC: can't open platform 30010000.sai: -6

root@okmx8mm:~# aplay -l

Hi chen

one can look at i.mx8mm dts file

fsl-imx8mm-evk.dts\freescale\dts\boot\arm64\arch - linux-imx - i.MX Linux kernel 

and check codecs connected to sai1:  ak4458, ak4497.

Best regards
igor
