Audio Managers for my Motherboard?

I use Realtek Audio Manager on my PC currently. But i cannot use my 5.1 speakers at its full performance… several times i have an issue with my rear speakers.. they don’t play.. and when i plug in the SUB/CENTER cable into the subwoofer’s back…. the subwoofer stops providing bass… I don’t understand why… SO i wanted to find a new audio manager for my PC compatible with my motherboard..
I use a <ASRock 775Dual-VSTA> motherboard….
Any help??
Answer #1
change the order of the speaker pins tat u r connecting to motherboard… or else use 5.1 sound settings in controlpanel->soundandaudiodevices->volume tab->advanced button..
Answer #2
yeah actually i tried everything… When i put the SUB/CENTER cable in the FRONT input,… NOthing changed except I Was getting RIGHT SPEAKER in the SUBwoofer… Thats pretty complicated.. I don’t get my films in 5.1, nor can i play Counter-strike in 3D environment..
I also tried changing the settings in the control panel,, nothing changed.. I just want to change top another software..!!!!
