The drive signal cannot detect the sai3 signal of imx8mm

[CheLL]

When using tinyplay to play wav files, wav is 48k 32-bit wide and single channel. But the driver does not detect the i2s signal, how should I debug?

Hi CheLL

one can try to identify problem with amixer, described in sect.7.5 Audio Mixer (AUDMIX)
