Microphone problem in calls, no sound

If you can do recording on (Sound Recorder  stock app) but not work on any app...maybe a software bug.
To understand you can Flash stock firmware with SP Flashtool and see how is.

Same problem here, no luck with Ms Windows 10 Pro 64Bit, using latest updates/drivers etc.

But I can flash my Umi Touch with Ms Windows 10 without any problems.
Weird... but can't flash my Umi Super with the same laptop/same windows 10/same drivers etc.

So installing it on a virtual machine, no lucks...

So for me only installing it on a old laptop with Ms Windows 7 Pro 64 bit, they are just working good.
I can finally flash my Umi Super.
