Well, I have spoken to my dealer today about this malfuntion, and it turns out that its the actual amplifier within the X1 that's causing this! I cannot believe that there is so many malfuntions with the X1. I will need the amplification card replaced on my machine. Great!
So if anybody has a similar problem to mine, then its more than likely going to be the amplifier card within the X1 needs replacing.
