5.1 Output from motherboard

[thebadtall]

Hello, there has been something bothering me for years but never tried to find out.

It is about the 5.1 audio output on the motherboard. Today I wondered how to listen from all the outputs, since only the green jack plays sound, all the others are muted.

So, I ask you, do I need special software to make them work ?
Suggest me Please a way to output the sound from those jacks!

Thank you

is your speaker 5.1 too?

No i've got a 2 channel tda7294 amplifier and a LM1875 BTL subwoofer amplifier, and would like to use the direct sub output to the sub, and the stereo output to my stereo amplifier.

check you install all drivers that need for sound card from your motherboard manufacturer website.
