It's a shame, but I've already rolled back to the version from Oct. 5. It works fine with extra apps I have. Let's consider it as a side effect of unknown nature that can't be cured at the moment. And, thank you very much for the nice ROM and for your time and efforts.I did and I saw Viper4Android FX running. So, I can't properly say it is not caused by it. I will better love a log without audio mods while reporting audio issues.
