Need help with 5.1 Sound

[Dilemas]

Hello,
Sorry if its not the right forum place to ask, but havent found proper place

Struggle with 5.1 Creative inspire T6060 , an old sound device.. So the problem is kinda known to people, but no solutions to be found.
The windows plays only 2 speakers from 5 ( front ones) .

• When you test sound, the all speakers (5 pcs. ) produce sound, clear and nice
• Downloaded proper driver, Realtek HD manager, set the system to 5.1
• Realtek HD manager able to play all five speakers with "Fill speaker" but the sound speakers produce is very low quality and not acceptable
• subwoofer have 3 output/input cords ( black, green, orange ) . My PC mainboard is Asrock B450M steel legend, ive put the cords where colors belongs (black is rear speakers, orange is subwoofer/center speaker, green is front speakers)
• Playing games works all 5 speakers, but when listening to music from browsers (Firefox, IE) from Windows media player, from VLC video software, the only 2 front speakers sound.. which is kinda annoying
• Placing black (rear speaker) cord into green slot, plays rear speakers

Any ideas how to make all 5 speakers work?

So playing games or doing speaker test, all speakers are working fine and quality is ok? You just want to play music from all speakers without it sounding poorly?

My Logitech 5.1 speakers has a button on the control pod to convert 5.1 signal into stereo so all speakers are playing. Speaker fill does similar. This is the only way besides setting speakers in Windows/Realtek to quadraphonic.

Have you tried adjusting the EQ in Realtek audio manager? I couldn't play an form of sound without adjusting this, the audio is just too bland. Sound Effects > EQ. From left (Low level frequency) to right (Mid to higher freq), adjust each to your liking. Or try one of the presets.

My EQ band in decibels are (Left to right); +3, 0, +4, +4, 0, +1, +2, +3, +6, +8

Update:

Only one game works 5.1 is Guild wars 2. only surround sound, each speaker produce different sounds but they all work.. and none of other games, only 2 front speakers working
