[Q] dead microphone after flashing aosp rom
hi, after flashing any aosp rom (slim rom, cm, paranoid, ...) my microphone is dead. i don't hear the other caller and he can't hear me. the microphone is fine because when i flash a tw rom afterwards everything works fine again. interestingly the mic works after the first restart after the flashing. as soon as i restart for a second time the mic is dead.
it does not matter wheater i flash with clockwork mod or twrp. i always make a full wipe (cache, dalvik cache, factory reset, internal memory, rom; basically all reset options twrp offers) before installing the new rom. i install the new rom (any aosp rom) with a new kernel that fits the android number and the correct gapps. sometimes i used the old kernel but it makes no difference regarding the mic.
i don't think i make anything wrong during the process because everything else works just fine. so far i always ticked the box to restore data with my google account, can this be the problem.
any clues where i go wrong? i hope someone can help me with that problem because i love my note 2 but i hate tw.
thanks in advance.
