Just installed Big Sur beta. I have two monitors connected via USB-C and now sound only works on one of the monitors and my macbook pro speakers. Catalina beta recognized both monitors and the laptop perfectly, but Big Sur has broken that. Both monitors still function as expected along with the laptop screen open; they function as three screens. But now I can only get sound out of one monitor or the laptop speakers.
