TRACKS GETTING MUTED BY NOISE FOR NO REASON PLEASE HELP

Hi guys i’m using Cubase LE 8 with Focusrite Scarlett interface. Everything was fine until 2 days ago.

Now whenever I open ANY project, here’s what happens :

I hear a NOISE in my headphones that switches from track to track like every 1-2 seconds, and this noise actually mutes the track its affecting somehow during these 1-2 seconds.

It happens if I play and even if I don’t play, the noise is always there, muting each track one by one every 1-2 seconds. And the volume and pan of the noise depends on the volume of each track.

It never happened to me before and this is killing me I can’t record properly anymore because it keeps muting tracks and it also reflects on the exported audio mixdown.

Anybody can help on this please ? I’m not an expert at all and I don’t understand why this is happening, everything was perfect, I never changed any settings…

PLEASE HELP. Thank you SO MUCH in advance

Hi,

It sounds like you are using any plug-in in the DEMO Mode.
