[Q] Low microphone volume
So after about an hour and a half of searching XDA and Google I have yet to find a resolution that doesn't involve me opening up my phone and cutting the rubber around my microphone. Allow me to explain.
Since I can remember - I got my S4 in December of last year - I've had problems with people hearing me, low record volumes and so on. I rooted and modded my phone almost immediately after receiving it and never really had the chance to test on stock TW, but this problem has persisted at *least* since I switched to KitKat about 2 months before it was pushed OTA via Carbon, Pac ROM, and Vanir. I have made it a regular habit of removing any DSP/preinstalled audio software and using Viper4A, but I was hoping to get some sort of lead before I flashed again, revert to stock TW, or took apart my phone. EDIT: I still have the exact same issue without V4A installed and using stock DSP/settings.
This problem was reported fairly commonly with the SII and the Nexus 4, but the methods I have tried to solve the situation (*#*#197328640#*#*; Trickster Mod, no physical blockage, mixer_paths.xml does not exist...) have yielded no results. I tested with TeamSpeak and Zello's outbound transmit volume and there's a dramatic difference, but how to adjust this on a system-wide level still eludes me. Google Now, Sound Recorder, SoundHound and other apps have difficulty with any sort of recognition even in ideal settings (eg. quiet environments). I had to virtually yell to set up Google Now's "Ok, Google" system-wide feature requiring me to hold the device at arm's length.
I'm posting because I haven't seen any issues of this nature reported for the S4. Could anyone point me in the right direction? Kernel tweaks? File modification I'm missing? Anything?
