Okay, here's an update.
I ran that terminal command, and this is what came out:

Not sure if I can identify any conflicts there. It looks like some of the familiar characters are there (VoodooHDA, the PS2 ones, etc). There is that one net.osrom.kext.Disabler...is that the same as the HDADisabler?
I installed those hardware monitors. The first one (HWSensor) didn't seem to recognize my hardware...it is only giving me HD temp (33C). Maybe I just don't have it configured right.
The iStat Menu is working better. Things look pretty normal though....CPU is hovering around 6% user and 4% system (just with Chrome and iStats running). Memory is 11%. I don't seem to be seeing any temperatures....maybe I need to get it configured. Or maybe OS X isn't detecting my temp sensors for anything but the HD? Either way, with usage being relatively normal, it seems unlikely that CPU loading issues are causing my laggy mouse/sound.
I think that about covers it. I'll wait to hear back from you guys before I go and start messing with my kexts....although the only ideas I have to try are to roll back the VoodooHDA to 2.8.4 or to try download/reinstall HDADisabler.
Thanks in advance!
Based on your terminal output, your system does not show any kext conflicts. Also, I believe that the HDADisabler.kext has been obsolete for quite a while.
Again, your sound stuttering issue might be caused by some incorrect settings within the VodooHDA.kext Info.plist.
Within the aforementioned Info.plist., change the Boost from 1 to 0 and Vectorize from YES to NO.
