I've recently started using Live and have just added the Edirol UA-1X USB audio interface to my G4 Mac.

It seemed to be working fine initially (for the first day), but when I booted up Live yesterday I got the following error message initially, and then when trying to select the audio ouput in the Live preference area:

"The device "USB Audio CODEC (0 In, 1 Out)" only has input channels. Live supports only audio devices that have at least on stereo output."

I unplugged the interface and plugged it back into a different USB port on the back of the G4. All seemed fine again.

Yet when I next booted Live, I got the same error message again.

Any thoughts?

Thanks,

Further to my earlier message I've tried the interface with a laptop Mac and it's working fine.

So the problem seems specific to the G4 tower (though both are running the same system version).

What I've also noticed is that in Audio Midi Setup, on the G4 tower when you select 'Properties for USB Audio Codec' it just shows one volume slider in the bottom right hand pane, whereas on the laptop is shows 2.

So, for some reason the G4 tower seems to think there's just one output channel.

Maybe there's a bit of software I need to reset on the Mac? Or a prefs file to delete?

This seems like a very un-unix-like solution. Are you running the same version of OS X on both boxes? What are the specs on each one? Perhaps the laptop is using USB2 and the desktop USB1?
