Alsa: no more recognition of the card (solved)

Hello,
I have a problem with the sound on an old computer. I installed alsa-lib and alsa-utils; I firstly tried "cs4236 Onboard PnP Audio" with alsaconf (but it doesn't worked), after I tried "legacy - Probe legacy ISA (non-PnP) chips" and everything worked fine (using aplay, a video on youtube, gvolwheel...). But I restarted the computer (I forgotten to run "alsactl store"), and no more sound. If I try alsaconf and after choosing "legacy", I just have the time to read "error: midinfo " (ou error: cannot load module opl3sa2) before the driver selection screen, and a fail when alsa starts. Here some error messages:

$ aplay

$ gvolwheel

I tried to reinstall alsa-lib and alsa-utils, kernel26, remove alsa from rc.conf, but no change.
Do you have a solution? Thanks

Re: Alsa: no more recognition of the card (solved)

A little up : I tried all the afternoon to get it work, but nothing fix it completely.
I executed "yaourt -Rc alsa-lib alsa-utils", reboot, "sudo alsaconf" and the sound was working. I tried "alsactl store", added "@alsa" inside rc.conf, restart again... And no more sound.

I tried few times to desinstall/reinstall again to check all the points of this wiki but it doesn't work anymore. I installed  "alsa-plugins", added "options snd-opl3sa2 index=0" inside /etc/modprobe.d/modprobe.conf but I still get "ERROR: modinfo: could not find module snd-opl3sa2" after choosing "legacy" 

Edit: my apologies, if I thougt that "cs4236 Onboard PnP Audio" doesn't work it's because all channels were muted -_-'
So after adding snd-cs4236 inside rc.conf everything works fine.
