I can't hear anything but the log out sound

I’m using openSUSE 11.1 and MSI K9N6PGM2 motehrboard which works good except the sound. Everytime I start this error message pops up.
Phonen
The audio placyback device HDA NVidia (ALC888 Analog) does not work. Falling back to default.

So I can’t get any sound from youtube or the games but when I log out/shut down it plays a little song. So at least something work.

SDB:AudioTroubleshooting - openSUSE

Check settings in Yast - Hardware - Sound

also the mixer in the panel - check the Master Channel and mixer switches

This is what it says
mattias-linux:/home/mattias # speaker-test -c2 -l5 -twav

I don’t have an old sound card and I said I can get the log out sound but not the others

Does that give you sound?

Clearly, that does NOT give you sound. But its typical that only one of the 3 tests in the troubleshooting guide give sound.

Did you try this recommended test, which is a link from the troubleshooting guide:
SoundcardTesting - AlsaProject

The fact that your log out sound works suggests to me your sound is ok, and this is likely a problem with either your mixer setup (check master, PCM and speaker volumes are set high in your mixer) or with your codecs for nominal multimedia applications.

Some news to the problem. I tried to tweak the mixer set up (like oldcpu said) by right clicking on the speaker symbol in the right corner of KDE 4.1.3 (Plasma) and turned everything on 3D surround and stuff. Then I pushed quit which I thought was save and exit. But now I suspect that it was exit the program. Then I tried youtube and I got sound. But it wasn’t loud enough so I thought that it was because the little speaker on the right corner only were at 77%. The icon was gone so I tried to find the program using YaST/hardware/sound and then the sound disappeared.

My theory is that when I log off openSUSE turns the speaker symbol program off before it plays the log out sound. That’s why I hear it. Can that be true?

No

What do you mean?

he means, have you carefully followed:
Multi-media and Restricted Format Installation Guide - openSUSE Forums

I’m not done with that yet but I saw two problems with it

  1. Videolan VLC 11.1 links to 11.0 but that can easy be corrected by the user by replacing the 0 with 1 in the URL.

  2. Packman thing isn’t an URL but if you click the link and copy the URL it should work, right?

Correct
We’ll fix that link

It seems like that did the trick. The sound works.

Should be good now

Great! Congratulations.

If its any consolation, this typically (with the occasional hiccup) only gets easier and easier the more and more familiar one becomes with openSUSE.
