well it worked yesterday when i tried it but doens't work again today. i believe it has something to do with power management settings. since nothign special was done yesterday, but monitor did turn off like it is set to. as explained before i disabled other featuers such as suspend or hibernate because they didn't work propperly anymore.
before sound worked well as long as computer didn't go into suspend.so i turned of suspend. and then after certian update hibernate didn't work propperly anymore as well.

Otherwsie it now shows dummy output inthe KDE mixer (don't really know it's name). it's also dummy output under sound settings, but the propper card with more volume levels (and all at max) is in alsamixer.

since the
sudo alsa reload -c
command seems to work i was thinking of making a script to be used as workarround.
