Just last week I solved this problem. In my Windows 10 laptop sound was fine. I was able to hear people in video chat. Even Microsoft Edge which is built-in browser for Windows was also working fine. But I was not getting any sound from Google Chrome. There can be various issues. But if there is no sound only in Chrome, then just check the below steps.

What happened in my case was that Chrome sound settings got disabled in Volume Mixer. So you need to right click on speaker icon on the task bar & then open Volume Mixer from the menu. There you should check if Google Chrome volume button is muted or not.
