What device do you have configured as the communications device? (Windows audio device settings)
WebRTC on Windows uses communication device, not default.

Thank you for reply. 
Communication device is also same as default.
I added screenshot with my settings.

In previously mentioned issue new comments also show same trouble.

Could you share your audio recording settings as well - how the mic is configured?

Anything which will help to solve the issue.

Hm, may be this is the cause - I use different input and output devices (because mic on my logitech is broken), and chrome selects corresponding output device for my recording device?

Are you able to reproduce the issue using appr.tc?
If not, which webrtc site do you experience a problem with?
Could you start a webrtc call there, then open chrome://webrtc-internals/ and capture GetUserMedia info from there?

guidou@ - could you PTAL?

Yes, it's absolutelly reproducable using appr.tc. Here is screenshot.

On latest canary everything is ok.
Also I've noticed that after chrome restart everything become ok in stable release.
And I thinked about usb devices and tried to plug different devices, but everything works as expected. Looks strange.

Hm, appr.tc is now working, but our service skorozvon.ru isn't.
How can I debug the issue? 

Tried testing the issue by navigating to https://skorozvon.ru/ but it seems the site accepts only regional(russian) numbers.

ateyhrib@ - Could you please provide test credentials/number to test the issue from TE-end. This will help us in triaging the issue further.

Thanks...!!

Strange, but our service now is also working correctly on the same machine - nothing changed from the previous test, even I didn't restart chrome.
