If you have Application Enhancer installed, you may need to update it. Check to make sure that your audio input and output are correctly set in Apple menu -> System Preferences -> Sound.

Thanks for your info, but the problem still occurs... Here's a rundown of what I did in response to your suggestions:
1) I do not have Application Enhancer installed, so that's not an issue.
2) As I mentioned in my first post, my sound preferences are in the same state as they were before this problem began, so that also doesn't seem to be the issue.
Also--As far as the document you pointed me towards goes:
1) My keyboard is basically new, so there's no dirt. Besides, since I'm getting on-screen (false) feedback re: volume, the button itself is obviously functioning.
2) The "keyboard" and "universal access" preference panes are in the same state they were in before the issue began--and they don't look to be the problem.
3) "International" Keyboard settings are indeed set to US English, as they were when I bought the machine.
4) As stated above, I do not have Application Enhancer.
5) I do not use speech recognition, so that's not applicable.
6) I just downloaded and installed the newest logitech driver for my mouse (a simple, 2-button USB mouse which was working perfectly before the issues began), and initially, the volume seemed to come back--but as before, the problem occured again.
FYI: The volume button seems to return to normal functionality randomly after any restart-related actions (shut down, restart, P-RAM, reset permissions, etc), but nothing makes it CONSISTENTLY return to functionality.
If anyone has any additonal thoughts as to why this is happeneing, please share! And please refer to my initial post to get any information you may need.
Thanks in advance, everyone!
No, you mis-read my post. the problem has been occuring BEFORE and AFTER that recent installation. I tried a new installation because the Apple.com support document you pointed me towards suggested I try that to rectify my volume button issues--it did not.
If anyone has any thought on why this is happening, please share. And again, please feel free to refer to my original two posts for details!
I would try running Alsoft's DiskWarrior. It does wonders to the directory as it rebuilds it.
You could also use Titanium Software's freeware OnyX (choose the right version for your OS X version to clean out a clogged system).
And there is always Preferential Treatment to fish out corrupted pref files.
That's about all I can think of at the moment.
Hi Diane! I just wanted to give you an update after reading your last post:
I didn't bother using Diskwarrior--partly because they don't offer a free trial, and partly because I've heard as many real-world horror stories as I have real-world good reviews of that product (both from colleagues): I didn't feel confident trying it at this point
That being said, I have used "preferntial treatment" in the past, so I tried that first. I noticed my Logitech preferences came up, but there was no OVERT indication that they were problematic, etc. Rather than take any chances, I trashed them. Unfortunately, after restart, the volume problem seemed to persist
I then tried ONYX, checking just about every "system optimization" option in the menu. After restart, the volume button began working again. I've used other optimization tools before, but this seemed to have at least some effect.
It's been several days, and the volume button is still working. I'm not sure if it was a combination of preferential treatment AND ONYX, or just ONYX, but I'm keeping my fingers crossed that my system works cleanly from this point on.
FYI: after a week of having no problems, the volume key stopped working again.
I was forced to use ONYX again, and it seems fixed... FOR NOW.
BTW, I noticed this recent occurance of the problem happened after running Windows Media Player... However, I've had Windows Media Player on my iMac for 8 months--and it's never caused any problems. I can't imagine it would suddenly cause the volume button to stop working this week.
If anyone has any other suggestions (aside form just re-optimizing my mac every time the key stops working), let me know.... thanks!
