Topic: Fireface 400: Alien invasion?
Hi reader!
I'm running a Fireface 400 (external power, with latest drivers and firmware) on my Macbook pro 13" 2.4Ghz Intel Core 2 Duo (Medio 2010) with Lion 10.7.4.
Audio output goes trough 2 analog jack outputs.
When I want to play some audio (itunes, Traktor, Ableton, about any program I guess) the playback sounds very good, for the first 20 seconds.
After that, it sounds as if my fireface is posessed by aliens.:o
Every 4 seconds there's a irritating sound coming out of my speakers, sounding like this:

After a couple of minutes the audio dissapears completely, the Fireface settings + Mixer dissapears and I can't see the interface in the sound options anymore. I always have to reboot to see the Fireface coming back.

I've tried this so far:
- Disconnect all other devices like midicontrollers, bluetooth device led monitors...
- Disconnect wifi
- All different sample rates.
- Bus powered vs external powered
- Reinstall latest drivers and firmware
-Laptop on battery, and with power adaptor connected
- Install previous driver updates
- Alien exorcism
Anyone can help me out?:roll
