Quest 2 casting function does not cast sounds from the Wwise Engine

Question

When people cast our game (currently in Alpha) via Quest 2, the audio running via Wwise is not cast along with it.
Only Vivox audio is heard, which we run via the engine (Unity).

There is an exception to this: When people start the game and THEN start to cast, it does cast the audio coming through
Wwise along with the Vivox audio. It only malfunctions if you cast your Quest 2 and then start the game.

Does anyone have a solution for this? Version is 2021.1.7
