Since I thought the problem was not having used the correct cable setting, I accepted a solution there, but then I fixed that and it didn't solve the problem.
I have a Fujitsu-Siemans Scaleo T, with SigmaTel Soundcard, in system it’s called SigmaTel C-Major Audio.
I’ve connected all cables correctly. The sound is set to 5.1. Also in the SigmaTel Jack Sharing, speaker configuration is set to 5.1 surround sound and the right part of the meny show the mapping of the ports to the 5.1 sound (not possible to affect)
I’ve tried a couple of DVD:s, on some I don’t hear anything at all, at other I get stereo-sound in left and right frontspeaker.
