sound sharing is not working

I think that it is happening because of network connectivity issue.

So I am having the same issue. I can play an audio file and or a video with audio through screen share and the out of nowhere it will stop working. However, if I quickly open up my sound tab and select Realtek Digital Output it will resume sending the audio through. I would normally then leave it in that sound setting but then again randomly it will not send the audio through. If have to then switch it back to the regular speakers setting. I have tried to disable either or speaker setting to see if that stops the problem, but it doesn't. There must be some problem within the input coding with Zoom I think. 

Me too - I have been using Zoom for 2 years now and sharing computer sound via the advanced setting, my bandwidth is great + everything as normal yet tonight it was working as if I had forgotten to share sound - coming and going for the participants.
Any thoughts?

me too- I have been using Zoom for a years and never had a sound sharing problem. Now I have a Acer laptop and the sounds works when I am not using Zoom, I can hear others on the call, I cannot hear the sounds for sharing from Chrome any more. I have follow all of the suggestion and sharing has no sounds.
