After upgrading to Windows 10, my subwoofer (2.1) doesn t play audio?

I just upgraded to windows 10 a couple days ago, and it seemed to run pretty smoothly. Firefox has been cooperating better than before and the Windows 10 edition of Minecraft works really well. Today, however, I plugged in my 2.1 home theater and tried listening to my music. Immediately I noticed a problem-- there s no bass. I checked the subwoofer, and sure enough, it wasn t working. Up until now, I hadn t used the speakers with anything familiar after my upgrade, so I hadn t noticed it. Now, however, it s glaring. I tried everything I could to fix it-- checking the control panel. Updating drives, disabling and re-enabling the device, generally everything under the sun --and nothing worked. The subwoofer won t play its audio, and thus I have no bass. My dad said he experienced a similar problem after upgrading to Windows 7, but he couldn t recall the solution. Does anyone else know the answer?
