Now I have only one problem.
I knew what makes aplay working sometimes and why I can not hear from my application.
The reason is only one.
If I run "alsactl restore 0", I can not hear any sounds but I can record through a microphone.
Thus, I changed to do "alsamixer -c 0" after "modprobe snd-via82xx" and unmuted and did level up of master, master M, PCM, mic, and mic boost columns.
Then everythin works fine. I mean audio device works in full-duplex mode.
PCM level did just unmute because CMI9739 does not have pcm things which is said from help.
So, my conclusion is that the only problem is related to the "alsactl" or alsa libraries which supports alsactl.
What can I do to solve no sound output on this kind of M/B?

bkna.

What ALSA version are you using? (maybe try a newer one) Regards, Clemens
