Realtek ALC888 5.1 Sound problems

Hello everyone,

I have been using Arch with KDE for quite a bit now, but i'm still a stranger to the sound system (maybe i'm just dumb and all),
i have a GA-965P-DS3 motherboard with a Realtek ALC888 8 Channel Audio on it, i have an 5.1 plugged in the back and a headphone in the front.
I rearly use the 5.1, about a month or so. First i used just plain alsa and kMix, it was all fine, untill the native Steam client comed and i noticed that
all games are running in a 7.1 setup, so ... i installed pulseaudio (i never liked it, but ...), then it was all ok, untill some kernet update.
Now i have the following issue, when i boot Arch, I allways get the KDE multimedia warning that yada yada yada device is not available, do you want
to forget, yada yada yada ... and i have no audio at all. So i have to open kMix, and at the Audio Hardware Setup i need to chose Headphones (however
it can't remember this setting, i have to make this at every boot), so far ok, now comes the 5.1, at headphone i have 2 channels at the 5.1 pluged in at
the back of the PC, when i chose 5.1 or whatever i have absolutly no sound at all (the channels are mutted every time i change the profile/connector
in kMix, i unmute them, even tried in alsamixer, everything unmuted, no sound once so ever, even tried the speaker-test -c 6 , speaker-test -c 2 nothing,
it only works on "headphones" connector and two channels). Here is an image of kMix:

fuser -fv /dev/snd/* /dev/dsp*

Anyone any ideas on how to get the 5.1 working? thank you, help is appreciated.
