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?

Hello MichelPM!

I understand what you mean, there's a bit of a confusion with these types of speakers.

Basically Apple had 2 types of Pro Speakers, one was for the iMac G4 & the other ones were for the G4 Cube (I've attached pictures to show the difference).

The Apple G4 Cube came with the USB Pro Speakers. They are extremely hard to find because they weren't sold separately, however if you ever see a pair definitely get them! An easy way to tell them apart from the iMac G4 speakers is that they have a black circle around the chrome speaker, and are linked to a small black Apple box that outputs to USB.

Here's the tutorial on how to connect the G4 Cube Speakers easily: https://www.youtube.com/watch?v=F_t4vF1LEDw

The iMac G4 speakers use a strange round connector that will only work with an iMac G4 or Powermac G4. However, you can buy an adaptor, but it isn't cheap (link below).

Hopefully this helps!

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.
