Well, first you will think "what the hell? Sound, but no sound?!", but its true: In the Sound-Manager ("Lautstärkeregler" in German) there are the bars that show, that some music is playing, but i have no output. No laptop-speakers and no external speakers are working. All regulators are on full, so normally it has to work!
I have a HDA Intel (i know, it sucks) sound chip with VIA VT1708S Codec.
Anybody got an answer to this problem?
P.S. I come from Germany and im still in school, so please forgive for my bad english
