I wanted to upgrade to 4.4.2 version of android so flashed Resurrection remix v5.1.0 and installed viper. Cant get the same quality i used to get in cm10.2. Also there is a distortion in output something similar to stammering.I also tried flashing omni rom latest nightly and cm11 M6, but still same problem persists. Please find me a solution for this. Cant imagine my phone without viper and dolby pro logic irs.
