It sounds to me like two related problems. The speaker problem sounds like either a connector fault, a marginal connection or a broken circuit board trace. These are all similar problems from an electronic standpoint, and are basically equivalent to "the connection is broken because some physical thing isn't making contact any more." The stuck right click is probably either a case mis-alignment or something which broke off inside and got itself jammed underneath the button. If you remove the case around the keyboard, you can examine the area to the left of the keyboard and look for the connection problem. A good, strong flashlight and a magnifier might help. Once the bezel is off, you can probably see what's going on with the button. If not, probing with a thin piece of plastic can be a useful and (most likely) non-destructive way of finding out.
