10.6.4 USB Pro Speakers (G4 Cube) don't work on Macbook Pro

I updated to 10.6.4 and my USB Pro Speakers (G4 Cube) don't work but they worked with 10.6.3. These speakers match this Macbook Pro beautifully and I'd like to get them working again.

System Preferences shows USB as an Output Source in Sound Preferences and I can turn the volume up and down but nothing comes out.

I created a new account, same issue. I even deleted com.apple.audio.SystemSettings.plist hoping that would fix it and nothing.

They still work as verified by my roommates machine that's running 10.6.3 :/

help?

MacBookPro5,1, Mac OS X (10.6.4)

Klaus1,

You said: "Your problem, hardware or software, may not be exactly the same as that of the original poster of this older thread".

That is - you did not understand that it is exactly the same issue while others like Rick Jansen1 did immediately and were able to help.

Please try to understand a thread before you tell others how to behave.

Thanks,

Karsten

Since updating to El Capitan, I am unable to add the kext file for the USB speakers and can't figure out a way to get them to work. The Kext Installer acts like it's working, but there's an AppleUSBAudio.kext that it won't replace. Any attempts to manually replace it are unsuccessful. If anyone has any idea how to replace the kext file, I'd really appreciate it. I have these beautiful speakers sitting here that aren't doing anything.

Think you have to turn off SIP (System Integrity Protect).

Okay,

I'll bite on this one since I still own an intact version of these.
