Need help to get the sound working

[mastablasta]

Hello I just switched the motherboard. I don't know do i need to do anything else in Linux to register this, because sound is not working (everything else works really nice). Let me give a better description of what is going on.

i need help with my sound card. i already asked on local IRC channel and got some help using alsamixer, but nothing changed. i thought this sound card is not compatible with linux (though it should be) so i tried Mint Live 8 - and SOUND WORKS. Don't have the 9 version, appart from LXDE. i will try that one as well, just to see if there is some Kernel issue.

Anyway my card is:

According to alsamixer

chip realtek ALC662 rev1
card HDA VIA VT82XX

according to preferences: VT 1708/A Azalia HDAC (VIA High definition Audio Controler)

Only this one dissapears after some time from the preferences. And then they behave like i do not have any sound card, so i can't change any settings. I am suspecting this is the old sound "card".

Please help.

EDIT> I just tested MInt 9 LXDE live session / sound works OK though it is a bit quiet and i cant really increase it much.

like i said card seems to be installed ok at the start but then it dissapears.

alsa mixer is showing master volume as 0. and i can't increase it!!!

There must be just a wrong setting somewhere in the system.

Do you have an add on card or just onboard audio? Is it a new install? Using old /home partition?
Right-click the alsa-info script link in my sig and "save as" to your user folder. Then run this command in a terminal:

sudo bash utils_alsa-info.sh

Enter your user password when prompted. Provide a link for the output or post it here using code tags.

Onboard audio. itsa new install (as in hardware install) using old home partition.

oh and here is the link the scrip gave me:

So this is a new asrock board? What's the model number?
Remove old config files:
Using a Terminal="Applications->Accessories->Terminal"

rm -r ~/.pulse ~/.asound* 
sudo rm /etc/asound.conf

If you've installed alsa-backports, uninstall it.
Now reboot and follow the alsa-upgrade link in my sig
to get v 1.0.23

Yes it's a "new" motherboad withold components. It's 4CoreDual-SATA R2.0. Has both AGP and PCIe ports as well as DDR and DDR2 ra slots. but can only hold max 2 GB ram. but perfect for upgrading.

rm -r ~/.pulse ~/.asound*
sudo rm /etc/asound.conf

"says cannot remove, no such file or directory." is this ok? should i just continue with next command?

Problem solved by a helpful ubuntu member on IRC channel.:

First i had to set the cvolume properly with this command:

sudo alsamixer -c0

And then save it:

sudo alsactl store
