volume keys Not Working

Ok... I can't be the only one experiencing this.

I have a Macbook Mid 2009, I recently upgraded to Mountain Lion. NO Problems til i try and use the volume control keys on the keyboard. If i hit the Increase (f12) key i get the Dashboard, and the other two keys do nothing.

I have found that when i restart the computer it works again for a short time (usually after i open an application it reverts to stupid and volume no longer works) i can control the volume from the menu bar (but really why should i have to do that)

I have reset the PRAM ... same thing. on restart the volume buttons work, when i open an application it reverts to what i described above.

HELP any one it is truly a nuisance and doesn't make any sense.

MacBook (13-inch Mid 2009), OS X Mountain Lion

UPDATE:

SO i restart my Mac and it seems that the volume control is working. It has nothing to do with starting an application as i previously stated, when the computer finishes starting up the volume keys just cease to function. Also to add the (f7-f9) player keys don't seem to work seemingly after the machine completely loads.

I have Sound and can control from the Menu, but NO Use of the Volume Keys.

It seems like it must be a startup thing, but not being a programmer i have no clue where to look to fix.

ALSO PRAM RESET does nothing to fix this. nor does the simple restart method mentioned somewhere else in this forum

FIX THIS Apple

Apple doesn’t routinely monitor the discussions.

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Hold down the power button manually till the machine powers off. Then power it back up again. It's a glitch and this fixes it.

You might want to consider starting a new discussion. Since this one is a couple of years old, less people are likely to look at it. A new post would be much more visible. You can link to this one.
