I find here: https://alsa.opensrc.org/DmixPlugin
this setup for ~/.asoundrc
# cat ~/.asoundrc:
pcm.dsp0 {
type plug
slave.pcm "hw:0"
}
# or:
# pcm.dsp0 pcm.default
# if "default" hasn't been redefined
ctl.mixer0 {
type hw
card 0
}

and it works now.
I can heare sounds from multiple applications at once.

Thank you very much, Robert!

Örülök, hogy segítettél. :)

Can you try playing through pulseaudio with:

aplay -D pulse test.wav ?

Yó napot kivánok! 

Take a look at https://alsa.opensrc.org/Dmix , dmix is the ALSA plugin you 
should use for this.
