Hello,I just installed windows 7 and i installed Realtek HD audio manager and after i restared computer it didn't open,i can't find it in control panel,and when i tried to open it in program files,it didn't open nothing happend,i tried to reinstall it and tried to manually install it nothing helped,and one wierd thing i noticed is that in MSconfig in program start ups it shows that it should start up,ive looked at other threads about this i tried everything but nothing of that helped,and yeah my Main green jack for sound dosen't work so i use optional one but i can't use it without realtek Manager.
