My Firewire has been working great for 2 years.

This morning when I played back a logic song (and itunes) it was only coming out of the left speaker and lighting up only on the left channel of my mixer.

All music plays fine in stereo straight out of my Macbook Pro (10.5.8)  headphone socket so I'm sure the problem is the Fireface.

I have played around with the Fireface matrix and it has highlighted the following.

There is no problem with playback - out 1 and out 2  light up fine.

When in the matrix: Out 1 goes to An1 and out 2 goes to An 2 - An1 lights up in the output channel strip but no An2
When in the matrix: Out 1 goes to An2 and out 2 goes to An 1 - An2 lights up in the channel strip but no An1
When in the matrix: Out 1 goes to An1 and out 1(as well) goes to An 2 - An1 and An2 both light up in the channel strip

If I change my main outs in logic to out 3-4, I seem to be ok

So I guess the problem is the Out 2....

Any solutions or does it point to a repair job??

Many thanks

Mike
