Hello !, my board NanoPi NEO (V1.0) no sound out for test by

Code: Select all


I get all sound card device by

Code: Select all

aplay -L

then try test by

Code: Select all

speaker-test -D "plughw:CARD=Pcm5102a,DEV=0"

and not success.

I test run alsamixer show "This sound device does not have any controls."


* I use last image file nanopi-neo-ubuntu-core-qte-sd4g-20170331.img


Neo has sound card,you need to download the new image.
You can use this way to test it.Download a song(xxx.wav) to NEO and play this song(aplay xxx.wav).
You also can try recording :
arecord -D hw:0,0 -f cd test.wav
aplay test.wav
