Topic: Fireface 400

Hello,

I have a problem with my **RME Fireface 400**.

In **TotalMix** the meters show normal signal.

However the audio outputs behave incorrectly:

* **Line Out does not play the music signal. It only outputs a robotic / distorted noise.**
* **Headphone output plays the music, but it also sounds robotic / heavily distorted.**

So the situation is:

* TotalMix shows normal signal
* **Line Out = only robotic noise, no music**
* **Headphones = music is present but with robotic distortion**

When I connect an external amplifier and increase the gain, the signal becomes louder but the distortion remains.

Has anyone seen this issue with Fireface 400?

Thank you.

Do you use an external power supply ?

Please provide a screenshot of Totalmix and more details about the setup.
