I don't want to sound rude but...it's the Arch way to read manpages and ArchWiki...also, provided topics. In fact, he gave you and answer. You shoud read ALSA on ArchWiki and PulseAudio chapters.

solve this problem !!! i read ALSA again and i do evry thing . but yet i have no sound !!!
then i make asound.conf into /etc with this line :

::::::::::::::
/etc/asound.conf
::::::::::::::
pcm.!default {
type hw
card 0
device 3
}

ctl.!default {
type hw
card 0
device 3
}

and .asoundrc into /home with these line :

pcm.!default {
type hw
card 0
device 0
}

ctl.!default {
type hw
card 0
device 0
}

and reboot ! but i haven't any sound yet ! then i go to vlc ! audio > audio device > by default discard all sample selected ! and i change that to 'HDA intel PCH , CX 20757 analog default audio device' then close vlc and open it again ! and i have sound this time !!! i go to site for waching .mp4 for another test ! in i have sound in site when .mp4 play ! but before this action i haven't !

then i remove asound.conf and .asoundrc then reboot system and open vlc with .mp4 and sound was !! and web too ! i can't understand what happen !! why sound work after i remove asound.conf and .asoundrc !?
The problem was elsewhere?
and when with vlc i selcet again discard all sample and close vlc ! i haven't sound in vlc but i have sound in web !
