imx8mm SAI1 录音失败

[yzg]

你好:

我在imx8mm使用sai1录音的时候遇到了问题，现在sai1可以正常播放音频，但是录音的时候会出现下面的情况，我测量了时钟都正确的 .

Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo

Hello yzg.

What is the BSP with which your MM is working please?  and also please share us your commands being executed while recording. It would be better to share codes that if you modify.

I here share a link, Add audio record driver in i.MX8MQ&MM.pdf, which includes a document for how to add drivers.
