Custom Audio Card SGTL5000 cannot output audio

Hello, we are using Orin nano module and custom board, SDK version is R36.3.0
The i2s4 interface is connected to the SGTL5000
I read the documentation:
https://docs.nvidia.com/jetson/archives/r36.3/DeveloperGuide/SD/Communications/AudioSetupAndDevelopment.html#device-tree-configuration-for-a-custom-audio-card
Here is the device tree file:
tegra234-p3768-0000+p3767-0000-nv.dts.txt (4.5 KB)
I executed these commands:

amixer -c APE cset name="I2S4 Mux" "ADMAIF1"
amixer -c APE cset name="H40-SGTL Headphone Playback Volume" 100
amixer -c APE cset name="H40-SGTL Lineout Playback Volume" 100
amixer -c APE cset name="H40-SGTL PCM Playback Volume" 100
amixer -c APE cset name="H40-SGTL Headphone Playback Switch" "on"
amixer -c APE cset name="H40-SGTL Lineout Playback Switch" "on"
amixer -c APE cset name="H40-SGTL AVC Switch" "on"
amixer -c APE cset name="H40-SGTL Capture Switch" "on"
aplay -D hw:APE,0 1ksine.wav

The kernel has error logs:

[  546.082020] sgtl5000 0-000a: PLL not supported in slave mode
[  546.082023] sgtl5000 0-000a: 278 ratio is not supported. SYS_MCLK needs to be 256, 384 or 512 * fs
[  546.082026] sgtl5000 0-000a: ASoC: error at snd_soc_dai_hw_params on sgtl5000: -22
[  546.082032] tegra-asoc: sound: ASoC: PRE_PMU: fe-pi-audio-z-v2-playback event failed: -22

Play no sound, but use the oscilloscope to measure the i2s4 has a signal:

root@edge-computer:/home/edge# aplay -D hw:APE,0 a.wav 
Playing WAVE 'a.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo

Is the device tree incorrectly configured? How should it be configured

3

I’ve found the reason. It sounds when it plays
How do I add this sound card to the graphical interface：Settings → Sound → Output Device

4

CAN YOUR MIC_IN WORK NORMAL?MY CIRCUIT CAN SOUND BUT CAN NOT MIC_IN。

5

My current MIC IN doesn’t work properly either

6

What is the performance of not working properly, my circuit can record, but it is extremely noisy

7

I recorded without any sound
Here’s my configuration

amixer -c APE cset name="I2S1 Mux" 0
amixer -c APE cset name="I2S2 Mux" 0
amixer -c APE cset name="I2S4 Mux" "ADMAIF1"
amixer -c APE cset name="I2S4 codec master mode" "cbm-cfm"
amixer -c APE cset name="H40-SGTL DAP Mux" "DAC"
amixer -c APE cset name="H40-SGTL PCM Playback Volume" 192
amixer -c APE cset name="H40-SGTL Lineout Playback Volume" 6
amixer -c APE cset name="H40-SGTL Lineout Playback Switch" "on"

amixer -c APE cset name="ADMAIF1 Mux" "I2S4"
amixer -c APE cset name="H40-SGTL Capture Switch" "on"
amixer -c APE cset name='H40-SGTL Capture Mux' 'MIC_IN'
amixer -c APE cset name="H40-SGTL Capture Volume" 6
amixer -c APE cset name="H40-SGTL Mic Volume" 6

Can you share your configuration？

It’s basically the same, but we’re using IIS2
