Hello and thank you in advance. I have a mt that I bought when walmart had them for 110. Here is my issue when upgrading to any custom rom (tried many different) My audio gets messed up when playing music it will pop and fade in and out even the audio from changing ap to ap will do the same. I know it sounds like a hardware issue but if I run stock I am okay. I have to mts and my one runs cm9 just fine. Again thank you
