Cracking Noise Change to Single oder Multi Player

Hi,

thx for fast answer. We have buy the Player Nov/Dec 2017. About the UTool i have controll that the Player has the newst Firmware. Today we i come too the studio and i check the Firmware. That would be fine, when this problem is fixed.

Other short question: Can i change the Master-Volume about all Outputs (exkl. Phone) on the Player directly?
