Several very popular USB WebCams with USB Audio support are causing
loginwindow to crash when the are plugged in or unplugged. The crash
happens in a call to CFStringCompare in
HALComponentHelper::DeviceIsNowAvailable(), which is part of a
XIOAudioDeviceManager::NotificationThread. This is logged in RADAR as
#2973082.
I'm wondering if anyone can tell me what string the HALComponentHelper
is trying to use? I'm wondering if I can stop using the
AppleUSBAudio.kext, and replace it with my own kext which sets
whatever string is missing, to make this crash go away.
This is a bug in the new Sound Manager in the QuickTime 6 Public
Preview. The quick work-around is to uninstall QT6. The harder
work-around would be to replace the QT6 Sound Manager pieces with the
originals.
