Audirvana for Windows 10 can't use apple TV

I use audirvana (trial) for Windows 10.

It sound great.

But I have a problem.

I want to airplay to apple TV.

The audirvana’s audio device can’t show apple TV.

How to solve it.

I use apple TV 3.
Roon can airplay to apple TV3.
But it’s expensive.

Hello @buick15078, we made the choice to use regulatory technologies in Audirvana and the typical behavior you quote is not possible since you can’t use Airplay with a windows 10 device because Airplay is a Apple proprietary protocol.
