Humming from the starter is more than likely your starter bushing in the transmission is shot and it's allowing the the armature to slop around and hit up against the side of the starter motor. It may very well be causing your battery to drain however, 11.92 volts is not what a battery at rest should have - should be able to hold 12 to 13 volts.
First of all, replace your starter bushing which pretty much requires you to pull the engine. There are ways to do it without pulling the engine but in this case, I would pull the engine and inspect the teeth on the flywheel and starter motor just to be safe. I'd also pull the starter and just do a general inspection to make sure nothing is amiss on it. I'd also check the torque on the flywheel, set the end play, replace the main seal and o-ring, inspect the clutch and throwout bearing. Also replace the input shaft seal on the transmission while you're back there. Once you have the bushing replaced and everything bolted back up and running, then you can tackle your charging problems. First, verify that your generator light is indeed good by pulling it out and putting 12v to it. You will not be charging if your light is burned out. Once you've verified that situation, then you need to check for 13.6 to 14.1 volts DC going into the battery. Anything less and your system will charge slower or not at all. I have a strong hunch your indicator light is burned out and your starter bushing is toast but I'm just guessing.
