The console throws an error when creating or selecting a game object with an audio source after domain reload or entering play mode.

Regression details

Regressed in [Internal link], which fixes a similar issue where selecting a game object with an audio source threw an error, but without the step of triggering a domain reload or entering play mode.

Repro

Open the ARC window (Window > Audio > Audio Random Container)
Dock the ARC window next to the scene view
Click on the scene view tab to make it back in focus, so that the ARC window is hidden
Enter play mode
Exit play mode
Create an audio source game object (GameObject > Audio > Audio Source)

Expected: No error is thrown in the console

Actual: An ArgumentNullReference error is thrown in the console

Note

Selecting and deselecting the game object will also produce the error after going through the repro steps. It will also occur after a domain reload, for example if creating, deleting, or editing a c# script in the project. Furthermore, opening the ARC window again will stop further attempts at triggering the error until you trigger a domain reload again.
