In previous months I've messed with all sorts of things I didn't understand (registry, services.msc, windows updates) trying to solve some other non-sound issues. It also doesn't show up in the "sound" >"configure" image, nor "test". Under "audio Channels" there is only one option listed "stereo", but this is a 2.1 (or 4.1? - I'm guessing 2.1 because its a laptop with 2 internals and an external sub).

Other than that notification, it doesn't seem to be recognized by the system. There is no other sign of the subwoofer except for a Realtek notification which tells me it's been plugged in or unplugged. There is a small electronic click when you plug it in or restart the PC.

The subwoofer is not being recognized by the system.
