Got my girlfriend a Logitech LS21 system for Christmas. It's a 2.1 system, but it's recognized in Windows 8 as a 2.0 system (it says there is no subwoofer connected). How would I go about getting the sub recognized? It plays some sound now, but it's so quiet you can't hear it without putting your ear right next to it.

It could be a problem with the sound card I've read somewhere. When the sub is turned down low with the knob on the back no sound, when turned up full you can hardly feel or hear the vibrations, so I decided to test on my mac they work fine, sub is nice and loud as it should be.

Does anyone have an answer on how to get the subwoofer recognized? I heard asio4all might work by playing with the sample rate? Or downloading new drivers but there are none on the logic tech site at the moment so maybe something realtek?

I'm going by memory here, so I may be wrong. (z313 as a reference, which is similar enough)

Simply put, with this system the subwoofer is not a separate device from the perspective of the computer. You plug the sub into the main line out/speaker port, and plug the front left and right into the subwoofer. Internally, they pass the lower frequencies to the sub and the higher to the front left/right. All the computer really knows is to send all output (all frequencies) to the line out.

Most modern desktop computers have a separate sub out. Since the sub in this system is not a dedicated device, you should not be using that port.

The drivers for your audio chip (usually onboard, depends on motherboard but usually Realtek - download from motherboard manufacturer website) are what you want to use if you want some finer control.
