I'm facing Audio issues during video calls, through whatsapp, Skype and hangouts.

The other person isn't able to hear my voice, but I can hear them. The video is very clear though.

I've tried with and without case, but have the same result.

My Nexus 6 and iPhone 6 have no such issues, which makes me think that its a problem with the phone.

Any suggestions?

Regular calls are fine, though? It might be an issue with the phone's secondary mic (at the top of the phone). That mic opening could be blocked or clogged by something, or the mic itself might be faulty. Try recording a standard video with sound, then play back the video and listen using headphones. Is one channel completely silent? If so, then the secondary mic (which was being used for stereo recording) is the problem.

No problems in calls on speakerphone or videos. I shot quite a few videos of my daughter and they sound good.

Will check the secondary mic. Thanks for the suggestion.

if speakerphone calls and recorded video audio is normal, then it sounds like the secondary mic is fine. Try selecting any one of those apps in Settings>Apps, tap Permissions, and make sure it has Microphone permission.

The issue is not yet resolved. They hear the audio at times, even that's with disturbances. No such issues when I use iphone or nexus 6.

Tried all apps like Skype, Duo, Hangouts & whatsapp.

It might be worth reinstalling the firmware. This might help: https://forums.oneplus.net/threads/h...a-loss.479265/
