Volume keys changing volume but no effect

[Ballens]

Ever since my cat decided to lay on my keyboard, the volume keys haven't been working right. Pressing volume up or down shows the volume bar moving on the screen, but it doesn't actually change the volume.
I have to go into the sound mixer and adjust it manually by clicking and dragging. Is there any way to fix this or am I stuck with it?

Since the type of computer is not mentioned I'd say a Desktop could have a replacement keyboard and if it's a Notebook a replacement keyboard can be installed but it's not as simple, have to do some disassembly. Also with a Notebook one can get a USB, Wired or Wireless, keyboard to plug in and use, just have to assure it's a multi-media version to have the volume keys, price could be acceptable or high. I'd try to borrow one first to test whether some other damage is involved.
