I also have a Phillips 5.1 soundcard, which is what you seem to have, sevi. My 5.1 sound was working perfectly for a while, on videos such as LOTR. Then I popped in The Italian Job one day, and sound was messed up, only going out the rear speakers. Someone with a similar problem mentioned that they have Creative Inspire 5.1 5300 speakers, but I don't see how that can be part of the problem. My system has been acting weird for a while, perhaps I should reinstall already. But does anyone know if this is soundcard specific? The one we have uses a C-Media PCI CMI8738-MC6 chipset. Fiddling with alsamixer controls has no effect whatsoever, except sometimes emitting a static sound from my center speaker. I believe it worked at one point, but was never sure.

Seriously, does anyone have any ideas on this? I will reinstall Slackware when I have the time, and report if it helped or not. I never had any problems with this sound card and xine surround sound output in the four years that I have had it.

Guignol: Could you send me the output from "lspci -vn" and "cat /proc/asound/card0/codec#2" (or whatever codec appears). I've been working on alsa drivers for a little bit now, and may be able to spot a fix for you.

Also, try downloading the latest packages (driver/libs/utils) from alsa-project.org. It "may" have already been fixed.

Ok all. I need to take a step back a second. I only just started working on the alsa driver stuff, and am currently only familiar with the Intel HDA audio spec. I'd suggest posting your other soundcard issues in the alsa-project.org bugzilla site. I might be able to help later, but right now I'm concentrating on HDA audio. Sorry.

Keep checking the alsa-project site for new release information.
