I am new to this forum but am in need of help. After I flashed the latest CM11 for my s4 there has been no audio when I receive a call. I can force close the app and then open it and put on speaker and there will be audio only through the speaker. When I turn off speaker, the screen goes black and there is no more audio. I have tried reverting back to stock and it didn't work. Any help would be greatly appreciated! I am running on MDK and was wondering if updating to ME7 would fix it? But I am unsure and want a better opinion than my own. Thank you for the help!
