alsa setup, my sound hardware isn't reconized

[trembb22]

I did install all alsa tce, did alsactl store and alsasound start give me:

Unknown hardware: "HDA-Intel" "Realtek ALC662 rev1" "HDA:10ec0662,8086d603,00100101" "0x8086" "0xd603"
Hardware is initialized using a guess method
/usr/local/share/alsa/init/default:51: control element not found
/usr/local/share/alsa/init/default:52: missing closing brace for format
/usr/local/share/alsa/init/default:52: error parsing CTL attribute
/usr/local/share/alsa/init/default:52: invalid rule

where should I start to fix this issue, maybe I need to build a new module but how
thanks

I tryied anyway alsamixer and used it to increase sound level at 100% everywhere.
than: speaker-test -Dplug=front -c2
produced noise sound on my left front speaker, that speaker-test switch to the right front speaker and there is no sound out of the front right speaker, only a click at beggining of the switch from left to right.
any idea?
it seems that my sound hardware work with alsa even if I got some stranges errors messages.
thanks for your help

now, how do we make alsamixer settings persistant accross boot?
thanks for your help on that one too.

found it!
set everything under: alsamixer
than
save setting into /etc/asound.state when executing: alsactl store
than
backup /etc/asound.state by adding it into the file .filetool.lst
than
it's done, setting are back the same after a reboot but dont forget to backup at shutdown


BUT I STILL HAVE NO SOUND ON THE FRONT RIGHT SPEAKER!!!

finnally I have a broken speaker, the right speaker is dead, so my problem wasn't a software problem.
this is closing the subject
thank you anyway
