10.5.7 update messes up speech recogniton component of rosetta stone

Question

I've been using Rosetta Stone for a while and there is a speech component to the program where, via the built in mic or a usb headset, you speak when prompted and the program analyzes your voice and tells you if your pronunciation is correct. With OS X 10.5.6 this particular component worked fine, but after installing the update the program now has a slower response time to my voice and more often than not incorrectly analyzes what I've said, requiring that I repeat each exercise about a half-dozen times before getting it right. I thought it was a problem with the program, but I was informed that this is an issue with version 10.5.7 and not Rosetta Stone, and that complaints have been spotted in forums having nothing to do with the Rosetta Stone software.
Could this be a bug with the update? If so, can someone direct me as to how to get a message to those responsible for correcting them. Thanks.

The post by Rasti,
"OK, for the Extigy issue ... it seems I have found a workaround.
Go to /System/Library/Extensions. There is a kernel extension for USB Audio, named AppleUSBAudio.kext.
10.5.6 contains version 2.6.0b11 of that module.
The 10.5.7. upgrade installs a new version, 2.6.4b11. Using a time machine backup
from earlier today, I simply reinstalled the old module...."
may describe the same audio problem you are experiencing.
The solution is not trivial and there is no guarantee it will fix your issue, but it might.
