I just bought a HTC One X and everything was fine until I flashed a custom rom. On stock there was no background noise when I used the headphones but after flashing a custom rom (cm11) there is a background noise whenever I hear music or when the notification sound is played. When I stop the music the noise persists for about one second. So my first thought was to switch back to stock but also there is now this annoying background noise. I think the noise came after I played with the dsp manager. Is it possible that the dsp manager damaged my hardware? Has anyone the same problem?
