Mic not working and buzzing speaker - Galaxy Note II Q&A, Help & Troubleshooting

Hello guys, I'm experiencing a problem with my sound in n7100. I don't think it's software related as I've flash the stock rom and the problem persist.
My microphone isn't working in any situation (voice call, voice recorder) and the device it's producing a buzzing sound by the speaker during the normal usage, specifically when using any kind of media.
I'm thinking to buy a new sub pcb that comes with a new microphone and maybe replace the speakers, but after some investigation I begin to think that the problem maybe be the audio ic.
Someone here have faced such problem in our loved n7100?
Thank you my friends!

LG KS20 strange sound during call (boosted microphone?)

Hi, I didn't found any similar problems, so I start new thread.
I have LG KS20 and changed some ROMs on it, but the problem remains the same.
When I call somebody or somebody calls me, he hears strange sounds similar to if I'd be near some big speakers, not echo, but you know, when you put the phone near audio speaker, you hear these sounds. After about 10 seconds it becomes silent and almost gone. I think it has something to do with inner microphone and speaker, I should say the microphone is overboosted, so when I get in call, it after 10 seconds automatically controls itself quiet, but when a new call, it starts over again. However I didn't find in registry anything related with mic gain control, I should try to minimize it's boost at first.
Do you have any thoughts how to fix that strange sound?
I have the same problem,
Does someone know a solution
And I have that problem, did anyone tried with handsfree is it same or is it better?
I should try that soon, also I will maybe try to clean mic somehow...
Anyone help?

Question Static sound from the speaker and earpiece

Hello! Recently I've bought Galaxy A52s and noticed one issue. During the audio playback or calls on low volume, and for a few seconds after the call or video has ended, there is some static and slightly crackling sound coming from the speaker and earpiece. Has anybody encountered that issue and is it a defect or it's just how speakeres work on? Should I return it or just ignore it?
Return it, never experienced this in 3 A52s
