Noise on Line Outs

Moderators: chensy, FATechsupport

Dear All ,
There is a noise on line outs from power up continuously and hazardous sound. when amplify the lines , it becomes much greater. I guess that lines tracks are not kept away from digital tracks in PCB design.

I got some success swapping the power-supply for a better one (from smartphone-powersupply to the official Raspberry Pi power-supply ) 5.1V and 2.5A
