My stock Samsung Galaxy s4 had no call sound at all, people couldn't hear me, and I could not be heard. I decided to root the device and try some custom ROMs however there has only been a decline in the circumstances. Now the Phone has no sound at all, notifications, any sort of app, or in call volume, I can still also not be heard. I've trie to flash a couple fixes via Odin and TWRP, to which I've had no success. I'm still rather new at this so any an help is appreciated. I'm presently running cyanogenmod, If yu have any input that could help please speak up!
