Your problem, as stated, is far too vague for anyone to be of much help to you. My suggestions to you:
1. Tell us specifically which audio/video players and codecs you have tried.
2. Tell us what you did to configure them.
3. Tell us which OpenSuse tools you have used to configure your sound/video system.
4. Tell us if you have had success playing any audio/video (ie, does the sound system work, can you play any kind of video at all, etc.).
