I've had my fire face 400 for around 2 years and never had any problem until now.

I'm having my Macbook with Mainstage and kontaktplayer running as my keyboard rig. In the fireface mixer i've always have the playbacks 1+2 up on the analog 1+2 outputs. I've also have an external module connected to input 5+6 and this setup always worked fine when I just plugged the fireface to my computer.

Yesterday it suddenly stopped giving any signal to analog outputs 1+2. I still hear sound from the external module though.
Is this a problem that someone else had? Going on tour next week and I'm really scared that it won't work.

I've tried several times to restart the computer and connect the sound card and it do works after 5-6 reboots. And I haven't changed anything during that time. I've also updated to the latest driver.

Anyone?
