Mac OS X 10.4.10: No sound from some FireWire audio interfaces
Issue or symptom
After updating to Mac OS X 10.4.10, some FireWire audio interfaces may have no sound output.
To resolve this issue, install the FireWire SDK 24 for Mac OS X from the Development Kits page.
Note: This download requires an Apple Developers Connection (ADC) account. If you are not an ADC member, you can create an account at no charge.
After you have installed the FireWire SDK 24 package, go to /Developer/FirewireSDK23/FireWireComponents/FireWire Audio 2.0.1 and install AppleFWAudio-2.0.1fc1-e8.pkg.
