========================================
Good Evening,
I'm facing this issue since months and it is bugging me up. My phone freezes before making a call or when receiving one and reboots every single time. Also my phone can't play or process a single video, it just shows the template and the pause button.No audio as well. Tried with earphones, both wired and wireless. Except all this the phone works exceptionally well. It doesn't hang anywhere else. Works smoothly. Fingerprint and camera works. No video recording.
Only on google chrome's Youtube site, i can play videos, but without audio. Else where like FB, Whatsapp, Youtube app and Insta, only photos load up. Not even a single video.
I didn't drop it nor put it in water. I mean no physical Damages. Games like PUBG work flawlessly, just no audio.
I have tried upgrading, downgrading, full phone system wipe and reflash. It comes back to the same position. Gave it to the service centre, it came back today with no solution. Please guide me.
I,m attaching the bug report. Please look up into this.

I did not have this problem.
And are you in android 8. If then update to the latest version and see if the problem is still present.if it is still present try resetting your phone.
If it is still present then I think it can be a motherboard problem.
Thanks for the reply.
Yes, I have tried upgrading it to the latest firmware. The problem still exists. Could be a motherboard problem, but all other things like gaming, surfing works exceptionally well. I'm giving this reply through the phone itself.
Could anyone find the problem from the bug report?
I think only the developer team or who build's custom rom can find the problem from the bug report.
Ok thanks
Microphone is low and no sim signal here.
Same problem.... while making whatsapp video call i can hear other person and he can't hear my voice... means my microphone not working properly....but in duo app its working fine...so with whatsapp only i hav a problem!
Edit:
It seems that if I pull up any video through MX Player it starts playing, without audio though. The audio button shows audio track as disabled and doesn't allow me to change it to Track 1.
I believe, if am not wrong, my device is unable to process audio anywhere. Do you think any part of the motherboard is at fault and could it be tweaked for that??
Is this problem Appear's only in mx player or in all apps like youtube.
Every app. In FB , YouTube and Whatsapp,they don't play at all. In insta they play sometimes without audio. Status don't play at all.
If I access YouTube through Google Chrome in desktop mode,videos start playing.
So basically any app that processes audio along with video isn't working. For eg: Whatsapp vidoes work if I play them via MX Player but no in the app.
Hence I can't place or receive calls too.
I guess MX player decodes audio seperately, so it plays videos well.
Can you clear the cache of your phone in the recovery and see if this problem is still present.
Or
Go to safe mode and see if this problem is still present.
