I'm using coaxial cable to connect Digi transformer to my receiver Yamaha rx-v375. Volumio 1.5 is installed in my Raspi B. At first it worked smoothly. But when I try to change song manually, big white sound occurs. If I touch the rca end on Digi side and rotate it a little bit, white sound stop and song plays normally. Moreover, while in most of the time there is no white sound between songs, but still sometime I hear white sound between songs. Any setting I should check?
