Microphone is not working when loudspeaker is on

Hi! I have a problem with my m4. The mic seems to turn off when i switch to loudspeaker during a call or if i start a fb messenger call with camera on. However the mic works fine with normal calls, i can record, use google speech etc. Mic test succeeded. Safe mode on and the same thing happens. I have put newest rom for central europe 26.1.A.2.147, wiped all possible data via flashtool and even on clean phone without any apps the problem still exists. I did not change any settings or so. It is just the mic not working when i wany to use loudspeaker ( the onr on the bottom of the phone). I also had issues with lower volume levels than in other m4, but here the rom update might help - i will see in fee days as i did rom update today. Do You have any idea what is wrong? The phone never had contact with water etc.

Google Now Launcher - Can't Open Microphone

I can't use the "OK Google" command within the launcher. It's not responding when I say OK Google. When I tap on the microphone icon next to the search bar, it says "Can't Open Microphone".

I've tried re-starting, installing a new build, and even tried clearing the cache for Google Apps, Maps.

This problem occurred earlier when I was trying to use the voice command to do a GPS search with Google Maps. Google Maps was acting all weird and couldn't locate my position then the Can't Open Microphone error began popping up. I don't know what to do.

I'm using the latest CM Nightly build from 09/29.

low microphone sensitivity ?

i recently bought a G4. I'm glad about it, but compared to my previous Note II i find that the microphone sensitivity is ridiculous , especially in voice messaging app like facebook messenger or whatsapp. Am i the only one who experienced this ?

Microphone not working in Hangouts? (Nexus ROM)

I have been on @ggow's Nexus ROM for a long time - think version 1? I saw recently that the bootloader was unlocked a while back, so I decided to tackle that and then upgrade to v4 so I can get Kit Kat.

I have Kit Kat, but still no microphone in Google Hangouts. I believe I remember seeing something back in Android 4.2.2 days on his ROM that there was some issue with the microphone driver - it would work in Skype, but not other applications very well.

Any ideas on how to get it working in Kit Kat?
