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
