Hay,
i installed 11.1 today and everything went normal, except the sound. During the initial install i already got a warning concerning the configuration of the sound.
I’ am alreading busy for 3 hours and tried everything on this site : SDB:AudioTroubleshooting - openSUSE
My hardware : Asus mb P4P800 : sound onboard :
82801EB/ER(ich5/ich5R)AC’97 audio controller
Please help 
OK, lets see where you are.
First, can you confirm that none of the 3 sound tests (2 x speaker tests, and the one alsa web site sound test) gave you any sound? If ANY of those tests give you sound then STOP NOW. READ NO FURTHER. Instead advise us. SDB:AudioTroubleshooting - openSUSE - how to test your sound
Second, can you run the following command twice in a konsole or terminal with your PC connected to the Internet. /usr/sbin/alsa-info.sh The first time run it with root permissions. When it asks to update, say YES. It will update itself. The second time you run it, when it is complete, it will pass you a URL in your konsole/terminal. Please copy and paste that URL here. JUST the URL.
Third, can you copy and paste the following commands into a terminal or konsole and post here the output: rpm -qa | grep alsa
rpm -qa | grep pulse
uname -a
cat /etc/modprobe.d/sound
With the output from the second and third requests I may be able to make a recommendation.
Thanks for the response. I have 3 years experience with ubuntu but this is my first attempt on suse.
First : nothing on the 3 sound test.
Second : I ran the script as root and updated it but got no URL but a text file
Third here the outcome :

Ok, thanks.
Before we do anything else, I need to you fix your mixer settings. If using kde it is kmix (and you may need to add some extra channels to do the adjustment) and if gnome it is alsamixer.
Please look at this:
!!Amixer output
!!-------------
!!-------Mixer controls for card 0 [ICH5]
Card hw:0 ‘ICH5’/‘Intel ICH5 with AD1985 at irq 17’
Mixer name : ‘Analog Devices AD1985’
Simple mixer control ‘Master’,0
Capabilities: pvolume pswitch
Front Left: Playback 24 [77%] -10.50dB] off]
Front Right: Playback 24 [77%] -10.50dB] **[off[/b]]
Simple mixer control ‘Surround’,0
Capabilities: pvolume pswitch
Front Left: Playback 0 0%] -46.50dB] [on]
Front Right: Playback 0 0%] -46.50dB] [on]
Simple mixer control ‘IEC958’,0
Capabilities: pswitch pswitch-joined
Mono: Playback off]
Your mixer has both digital audio (IEC958) OFF and Surround sound at 0%. I highlighted them in a sandbrown colour. But more important you have your Master Volume OFF. I highlighted it in red. That is guaranteed to mute your audio. You need to turn that ON.
There is no point in looking at this further until you switch that ON, move up the volume, and then run those 3 speaker tests again. ONLY after you have done that, and have confirmed that NONE of them give you any audio, is it worth considering other fixes.
If they give no audio, please advise, and we can go from here with other updates to apply.**
When running those tests, also try listening with a head phone (separate from the speaker) and also try the test with root permissions.
Now I’ve got sound. Strange.
I checked the master volume (computer>yast>hardware>sound>volume) and it was on (100%) I clicked on test but nothing.Then I opened the terminal with the “alsamixer” command. Saw a bar and decreased it to 75% and took the test in the commandline
speaker-test -Dplug:front -c2 -l5 -twav
This worked. Also this
speaker-test -c2 -l5 -twav
worked. i opened a mp3 file with vlc but the sound was no good.with amarok much better.I also opened a flashmovie with the mplayer: sound ok
But when I try to take the sound test via computer>hardware : nothing.
Do you think there are some adjustments needed.
sorry if I make some mistakes writing English, I am used speaking Dutch 
Me again.
I had to repeat the above procedure after a restart. Something wrong in the configuration?
YaST has a known bug in its sound test, where that sound test does not work for all sound hardware.
I believe the same is true for some of the desktop configuration menu’s, in cases where there are sound tests there, those sound tests do not work for all audio hardware.
That is why I always recommend these speaker tests here, where typically 1 of these 3 tests will work (and only 1 is necessary to work to prove sound functions): SDB:AudioTroubleshooting - openSUSE - how to test your sound
In the case of vlc, you should check the output audio module/engine as it is possible you can change to an audio API that works with mp3.
Also, reference multimedia, one needs to be very careful with openSUSE repositories. Two very popular repositories for multimedia are Packman and videolan. Unforutunately in some cases they are not compatible with each other, and hence it is best to stick with one, and NEVER use the other.
Since Packman tends to have more applications, I always recommend users ONLY use the Packman repository (in conjuction with OSS, Non-OSS, and Update repositories) and NO others. None. Just those 4: Packman, OSS, Non-OSS, and Update. Disable videolan.
There is guidance here for installing those: Repositories/11.1 - openSUSE-Community
Once those 4 are setup (and others disabled), one can go to YaST > Software > Software Management, and change the “filter” to “search” and then search for and install the Packman packaged version of the various applications (amarok, amarok-xine, amarok-packman, libxine1, xine-ui, smplayer, vlc, libffmpeg0, ffmpeg, libxvidcore4). One can tell the Packman packaged version by a “pm” in the version number.
I checked the repositories and they totaly match your recommandations. Many thanks.When I open
alsamixer
in the terminal I see : card : PulseAudio
chip : PulseAudio
Should I change this in vlc (currently alsa audio)
Furthermore when I restart the system, the audio remains active. Idon’t know what caused it to put the master volume muted.
I don’t know.
Use what works best on your PC.
good advice.
Use it often 
Thanks for the very detailed help
