I dont know how I should capture my problem so I will describe it:
When Im hearing music/watch videos or do anything where a sound gets played on a custom ROM I will be able to here a consistent rustle in the background. Quieter -> more rustle. Louder -> less rustle. When I use headset no rustle at all.
So thats my problem and NO my device is not broken! When I switch my ROM via backup its instantly fine again. I tested CarbonROM and Resurrection ROM when I use the stock 6.0.1 Firmware with root no problem at all.
Could be the problem because of Sonys Clear Audio feature? Should I backup to 6.0.1 again and disable it? What should I try? Help please
