No 5.1 sound on speakers

[Rodark]

Hey there. Got an msi b450 gaming pro carbon ac and some old creative sbs 580 5.1 speakers
Ive tried many things, including removing drivers + nahimic and re installing but i still dont have 5.1 sound. In some games i even have to lower to stereo from realtek audio console, so i can have proper audio. Obviously i have set it to 5.1
Two speakers plus the subwoofer work, when i click the test on realtek the sound of the other 3 speakers comes out from the 1 that already works, but muffled like from a far corridor or a bathroom or something. Yes the speakers are old, but they should be ok. The connection on the back of the mobo is ok as far as i understand it, since i followed the quick start guide from the speakers( pic link). Also of course i have switched to speakers realtek audio on the sound option on the windows taskbar...
