USB microphone problem on Mac OS X 10.5.2 Leopard

Apple.  Please help fix this problem.  It is causing issues on many USB headset devices.  Unfortunately it has been raised as an issue on some of our wireless headset products, basically users complaining about robotic voice, or scratchy voice, or even muffled voice quality.  In doing some research, it is clear that this is a problem with other USB-Audio devices as well.  All signs are that it points to some emergent issue with 10.5.2 Leopard and so far, Macbook Pros.  We'll see if the fix is identified and resolved.  Right now it is a nuisance for Skypers, podcaster, etc.
