[i9506][Q]Awful headphones sound after flash

I have a i9506 and it had perfect sound quality. After going from Lollipop DOF1 to DOF2 with arther97 kernel the sound trough headphones got really bad.(if 100% is perfect, it is at 10% quality). I have tried flashing older roms. I even tried to go KK again but it always has bad sound. When the phone is doing nothing its ok, but as soon as it has to make a sound there is a pop in the right channel and lots of noise, after about 5-6 secs of silence(headphones still make noise) it pops again and goes to normal. I tested the headphones and they are ok. It makes the same problem with other headphones and my PC stereo. There are other bugs like poping when chainging songs. I have tried v4d but it didnt fix it. It just made it bareble. (~70% quality, no poping between songs), but it still pops like hell and has lots of noise. The jack is clean, and its connected normaly to the motherboard. I have tried CM roms, kk roms, other kernels and no succes.
