My mic doesn't work with Google Duo

[Lassel]

I am using CM14.1 Samsung GT-I8730 and the mic of my phone is not working with Google Duo app. The mic works well with other apps. If I use Bluetooth HF or Headphones with mic then others can hear my voice. It didn't work with CM14 either. It worked one version of CM13. Don't remember which version. Any help?
