Uncheck "Disable video output when in the background". Switch to the Audio Hardware tab and choose "PostStream Audio" as the default output and master clock.

Setup your NLE to send video - Davinci Resolve

Output in Resolve is not handled as a video out, because 3rd party output devices are not supported by Blackmagic. Instead, output is achieved by placing a passthrough OFX filter in your node tree. The PostStream ofx node should be last in your node tree, to ensure that it reflects the entire tree's corrections. So that it works across multiple clips, it is recommended to place it in a timeline node. It will affect render times, so it is recommended to disable/delete it before doing any renders.

Audio is assigned in the "System Preferences". In the system tab, make sure that "PostStream Audio" is listed as the Device. This can be done in app, or by assigning as the system output and choosing "Use System Setting"
