In one of the beolab 5 speakers (connected through the beosystem 4), I get the following problem several times per day: a loud cracking noise/sounds, as if someone is shooting from a gun-machine for about 0.5-2 sec (sounds like 3-10 "pistol shots".
I have no idea what to do and it’s really annoying me?
Maybe someone else already had a similar problem and knows how to solve it?
