I've searched the Apple support site and here, but can't find this particular issue, so I'm hoping someone here can help me out (there is a good chance I'm not searching for the right phrase, I guess). The Volume Up, and Volume Down keys on my keyboard no longer work. The Mute key makes the Volume Mute logo appear on the screen, but dosent really do anything to the volume. I'm running OSX 10.3.9 and havent loaded any new software or anything lately. The latest thing I did was update my Quicktime, but that was early last week, and I went the whole week after loading it with no problems. When I left for the weekend, everything was fine. I have repaired permissions, and shut down/re-started. Immediately after this post I'm going to zap the PRAM to see if that does the trick. Any suggestions would be appreciated. Thanks in advance.
