Recently the subwoofer connected to my computer has stopped working, despite the fact that its worked fine in the past. The two other speakers i have currently hooked up to the computer work fine. Weirdly, whenever i plug in the subwoofer in the back of my pc, the configuration settings (where you choose if the device you plugged is a speaker, headphones, mic, subwoofer, etc) appear as normal, despite the sub not working. The model of subwoofer is an INSPIRE T7700, made by Creative Labs.
