Convey up the volume control panel that displays all the inputs. Mute all that you don’t need: series, microphone, CD player, etc. If the clicking goes away adjoin one at a time back in until you acquire the noise yet again. I had a difficulty with static on mine. Ended up being the microphone volume was the entire gradient. Since I don’t employ or require a microphone at present, I just muted it and static leaved. I have also seen this with the CD player volume up all the way.
