I applied all motherboard's drivers from original MB's CD installation.
So I even tried to update Realtek high definition sound driver but it says it is the same version as I already have. The strange thing is it is happning to all 3 OS I'm working with and the last one -OS I installed just few days ago.
The settings in bios are:
High definition audio enabled
front panel type HD audio (iven the front panel is not connected only rare panel MB)
SPDIF_OUT MODE SETTING HDMI output
It is interesting that only video program's sound does not work.
