My situation happens when I switch from playing a video in YouTube to Davinci Resolve.

Steps to reproduce.

* Add clip with Audio to Davinci Resolve
* Play clip (sound works fine)
* Open a video in YouTube on Chrome or Safari
* Play a video
* Switch back to Davinci Resolve

Sound does NOT come through speakers any more

See end of this post for a TEMPORARY fix


Alternative Steps that do NOT reproduce the issue

* Add clip with Audio to Davinci Resolve
* Play clip (sound works fine)
* Open a video in Finder
* I used the same video as from YouTube, only I downloaded it to my computer
* Play a video
* Switch back to Davinci Resolve.

Sound Works

I have followed some other threads on Davinci Resolve not playing sound.

I have tried the ideas mentioned in those threads such as:

Patch Input/Output



I have also tried speaker setup in Video & Audio I/O



Using local video does NOT reproduce the issue

* Add clip with Audio to Davinci Resolve
* Play clip (sound works fine)
* Open a video in Finder
* Note: I used the same video as from YouTube, only I downloaded it to my computer
* Play a video
* Switch back to Davinci Resolve, sound Works.
