Question: Is it possible to use multiple CastPlayers at once?

Hello,

I have seen very little info on this on the internet so I thought I'd ask the experts.

I have an audio only application that can have multiple instances of exoplayer instantiated at a given time to overlap the audio output. (think of an audiobook with a soundtrack played over it) I manage all of these instances via a manager in a MediaBrowserService.

I am interested in integrated Google Cast into my application with the recent news of conversational actions being shut down. I have taken a look at the UAMP repo and see they instantiate their cast players and switch between the exoplayer instance / cast player instance depending on the cast selection from the user.

I was wondering has anyone tried or know if multiple CastPlayer's can stream to a speaker at once? I've seen plenty of examples of just switching a single exoplayer instance but am curious if multiple instances would work?

Edit: What I am looking for is similar to how the google home app can capture the entire audio output and stream it to a device

Thanks!
