Has anybody had the problem of the digital clicking from the volume control coming through the speakers. I guess the mute should activate as everything seems to have a mute from the analogue switch LC7822 to prevent output of stuff on the speakers but the mute circuits are really complex. The pcb is very badly manufactured as if it is over etched and not cleaned properly before being screen printed because I have fixed one fault but a wide track lifted off real easy with very little heat requiring extra repair. I dread touching the board so would like to go straight to the problem if someone has seen it before.
