Asimov got a reaction from mhc in Enable sound on Banana Pi M2 UltraI can enable bananpi M2 ultra sound (headphone and mic on pcb) You must add this on the dtsi file.
dma: dma-controller@01c02000 {

reg = <0x01c22f00 0x4>;
};
Then modules that must be loaded are
sun8i_codec_analog 24576 1
sun4i_codec 32768 3
snd_soc_core 118784 2 sun4i_codec,sun8i_codec_analog
snd_pcm_dmaengine 16384 1 snd_soc_core
snd_pcm 65536 2 snd_pcm_dmaengine,snd_soc_core
snd_timer 24576 1 snd_pcm
snd 45056 3 snd_timer,snd_soc_core,snd_pcm
soundcore 16384 1 snd
to test the player execute that to check the sound
$ aplay /usr/share/sounds/alsa/Front_Center.wav
then execute
$ alsamixer
to control the volumen and gain
To enable mic do that.
1) open alsamixer;
2) press "tab" to switch to capture;
3) press "bar" on the first capture channel;
"L_____R" red sign should appear;
4) select by arrow key MIC as the source of the first
input source;
2) record a test file:
arecord -f cd -D hw:0,0 -d 10 test.wav
play it back to test i.e.:
mplayer test.wav
Thats all ...
best regards Asimov

Asimov got a reaction from guidol in Banana Pi M2U - A40 - ethernet interface problemI have a Custom SOM with A40i because we change from R40 to this core and the kernel that I use is 4.14 Stable or development on 4.18... and itś working ok... I don't change anything to run kernel on A40i because is the same (pin to pin compatible) with R40...
