Amd OverDrive
This might or might not have anything to do with the sound problem - but I figured it doesn't hurt to remove error conditions in Event Viewer (Sometimes it is "Much Ado About Nothing", because some errors have very little effect on system behavior).
You could check in Event Viewer again, just in case re-installing your Catalyst drivers corrected the version issue. If you are still seeing those AODDriver4.3 errors, if you like you can make a backup - and then try the Registry edits that remove the error. The method is from an old Tom's Hardware forum thread, and I put a link to it in my post #4 in this thread.
Corsair SSD Diagnostic
Since your SSD is your boot drive, it's likely the drive receiving the error from around the time Windows is starting up. It's also more likely to designated drive 0 (which is the drive number indicated in the error message from Event Viewer). You can use the
Corsair SSD Toolbox to have a look at the drive's health. It can also update the firmware, if and when necessary - if one is available that applies to your exact model. But by all means, if a firmware update erases the drive, create a system image backup of it beforehand, should you decide to try such an update. You should be able to run diagnostics without disturbing the data on the SSD at all.
Downloads
By the way, when you look at the Summary View of Errors in Event Viewer for the SSD drive errors - how many errors does it show each time? Is it limited only to startup? Do you see twenty or thirty retries (same error recurring over and over very quickly - within a matter of seconds)? Or?
Audio card
Some gamers upgrade their components often - if any of your friends have an extra (compatible) sound card lying around, perhaps they'd lend it to you: you could test things with the onboard still disabled, the Audigy removed & uninstalled - and see what happens with a different sound card.
Overclocking
Since you have very capable components that are often overclocked for extra performance - if you have overclocked any of your hardware, try going back to stock speeds while testing the stuttering issue.
That's about it for the moment....
