high pitch noise from main microphone

high pitch noise from main microphone

I have a Sony Xperia XA2.

 

Now after about 3 months use the (main) microphone started to add a high pitch noise: 

- it appears in sound recordings

- it appears in video recordings

- it appears when testing the (main) microphpne in Service mode.

 

By cheking the recording (converted to wav, then viewed) I found value-spikes with about 714Hz frequency:

At the beginning this noise was not there.

 

The service mode test showed no noise at the secondary mic.

 

Restart, "safe mode" have not helped...

 

How can I get rid of this noise? 

 

Where does it come from?

- apparently not from applications as mic test also demonstrates it

- from mic as HW?

- from A/D conversion?

- from mic device drover of Android?

- from system function of Android?

- or???

 

Thanks a lot, 

 

Henrik

 

ps: I wanted to upload a sound file, but  did not find how to attach it

@Henrik_the_Som 

 

have you considered repair the phone with Xperia Companion?

Hello Uliwooly,

 

Not yet, not at all. First I have to check out what this Xperia Companion is.

 

Thanks a lot for the hint.

 

As the mic test in service mode fails with quality, I do not have much hope, but I am going to give it a chance.

 

BR, Henrik

Re: high pitch noise from main microphone

I have installed Xperia Companion. It suggested Android update, which I did - but mic issue remained the same. (the road to this update was not smooth, but never mind...)
