The problem is that the changes aren't kept if I shout down the system, but they are kept if I reboot (anyway I didn't give this much try I noticed twice)
On the other hand I am trying to plug a Headphone (also wanted to conect two more pair of speakers) and I don't get any sound. I don't know what to change in "alsamixer" (where I tried unmuting by pressing "m" in headphone column, also tried to changed "aux jack" by setting it into back south), neither in "pavucontrol" (where i have tried everything). This card has for entrances or "female jacks" (hope the term works, I am not an English speaker native) they go in this order : black = aux out , silver = center, blue = surround, green = line out, silver = line in, pink = mic in. I have unsuccessfully tried plugging the headphone in each one of them (although later I learned that "aux out" should have an internal connection)
I have contact VIA by email , they told me they didn't built that chip, then I tried Encore , the device doesn't exist in their web site, I wanted to ask them for specific drivers.
this is my system

Here I leave screen shots to show you what I see, this parameters are good for the left speaker problem (so I can get sound) but remember that doesn't last after shouting the system down I am still worried about a headphone or extra pair of speaker line.
The image pics windows are in spanish where your read "control de volumen" that is "pavucontrol" , where you read "preferencias de sonido" that is "sound preferences" from the icon panel.
I cannot paste the images with since it says it cannot determinate the size so I attached here the most important pics.
Thanks in advanced.!
