The stereo signal is delivered to the sound system and a subwoofer signal is sent to the subwoofer (The subwoofer produces bass) BUT when the subwoofer is on max on both my laptop and the amplifier inside it produces a small amount of sound. I have 'Bass management activated underneath the diagram of a 5.1, I have 'Front left and right' activated under 'Full-range Speakers' and then I have 'Subwoofer' ticked under 'optional speakers'. The sound system is set to 'Front Speaker Out' the subwoofer is set to 'Centre/Subwoofer out' sound is delivered to both outputs in the speaker configuration '5.1' on Realtek Audio manager. One of those ports has my sound system plugged into it with the subwoofer unplugged, another port has my active subwoofer plugged into it. I have a Laptop with 4 ports on the side. Next time, do some research before you go out buying. on 2.1 systems the subwoofer shares the same input as the front speakers and just handles the low tones.Īs far as a solution? you could try using a 3.5mm splitter and that *might* work. meaning it will play only through the green port on your pc. The reason why you are not getting any response on music is because almost all music is stereo only. This is why you can not seem to make it work as a 2.1 system. The orange colored port is reserved for the center speaker and subwoofer connection only on 5.1 or 7.1 setups. Because 2.1 and 2.0 sets connect up with only one 3.5mm plug.
