Hi Zoltán,

that just sounds like a mis configured Xine to me. Xine can be 
configured to use different outputs for Mono/Stero and 5.1 sounds.

You can also configure ALSA to route the audio differently depending on 
the number of channels, but that isn't the default and if you configured 
it like this you probably would remember it :)

I can't really see a way how this can be a hardware problem either, 
cause 5.1 audio pass through is handled mostly the same as Stereo.

I suggest that you check your Xine configuration, you should find 
multiple setting for selection the output device (Mono/Stereo/5.1/7.1 
etc...) make sure that they all point to the correct hardware device.

Regards,
Christian.
