Battery drain with any kind of audio

Hello guys, so i just flashed temasek's rom after a mega wipe and sd card format..

So far the battery is good in every way but when i use youtube, listen music or even receive lots of messages in what's app i get lots of audio_out2 wakelocks, it shows like media server in the battery stats...
It's using almost the same amout of the screen when i'm watching youtube videos..
