So i tried a bit swaping cables and so on. I had a green (stereo output) , blue (stereo input) and red (mono input) and luckily my mainboard turned out to have a multiusage for the blue stereo input so that i could put my second pair of speakers in the blue one.
Evening folks from Germany. I'm a student in mechanical engineering and short on budget. Although I'm quite into technology and PCs i can't figure out this problem by my self.
Setup:
No sound card. only mainboard outputs + front audio output
2 speaker sets: 2.1 and 2.0
What i'd like to have...
