My right computer speaker took a spill. There is static and the volume won't turn up.

When plugged into the power, there is static and buzzing. When also plugged into the computer, there is static and no buzzing, and I can hear music very faintly. This is unaffected by the position of the volume knob. The volume knob itself is PRESSED in from the frame a ways, I don't know if it was already LIKE that. I think it wasn't, but it doesn't seem like it's MOVEABLE at all (BACK into place, I mean - it still sturns like it's supposed to). When the left speaker is plugged into the right one, the left works well and the volume knob does have the desired affect on that speaker, with no change in the static from the right one.

What is wrong with my speaker? It sounds like something must be disconnected. I'm hoping it's a lose wire or something else I can fix. Also, PLUGGING the left speaker directly to the computer works but is unamplified (not ideal)- is that okay to do?

Any help or further information is much appreciated.
