Thank you for helping me.
I cannot play sounds from the computer.
I have it seems two cards on my system that manage the sounds.

One of them has its output on the front panel (and according to what i read on the gui sound manager of gnome it should be called 'NVidia CK804 (Alsa mixer)'

The second one according to the same source is called 'Realtek ALC850 rev 0 (OSS Mixer)'. Its output is a 5.1 on the rear side of the computer. This last one is built altogether with the mother card which is a 'Asus A8N Deluxe SLI'.

I would like to use the one on the rear side ie the 'Realtek ALC850 rev 0' but it doesn't work.

Is this card can be driven by ALSA, if so how to make it recognized by ALSA ?

Presently, when i try testing the sound with the gui interface 'sound' of Gnome it hardly plays anything (almost unearable) if ever it plays something.

I wonder what to do for having normal sound through the 'Realtek ALC850 rev 0'.


Thank you to everyone who would had a clue for fixing this problem.

I wish to every reader a nice day.
