just went from CM12 to Resurrection Remix Oreo, noticed some issues with the microphone quality too. now i'm not sure if there is a fix already included in the ROM, but the microphone sounded very low quality and compressed to hell, like there's something trying to hide that microphone is very quiet. AudioFX kept crashing when any audio was being played, removed that, now the microphone is just very quiet and low quality, as described in this thread. Now, besides flashing i'm pretty much a noob and don't know how to apply the fix you guys described. would it be possible to put the fix in a flashable zip?
