Lost in call sound slightly random ??

[Guest Ricey155]

HI all my nexus 4 has been great but it has a problem with in call sound (it comes and goes but fine with speakerphone) 

 

I've flashed many radio's / basebands and roms and it cures it for maybe a few calls then goes back to silent (sound only heard via speaker) 

 

the sounds works fine with a headset 

 

 

any glues I've searched everywhere and nobody has a solution - I've used soundabout app doesn't help, I've used the NEXUS radio flasher from the store (modem flasher) flashed every modem available still no solid solution 

 

any help would be appreciated

No clues then ? Might roll back if no cure for 4+
