When using the Steam Link app on an iPad Pro, I can't hear any audio that should be streaming from the host. I can hear the audio of the Steam Link app itself, and the audio plays fine on the host computer (MacOS), but I can't hear any Big Picture UI or game audio in the Steam Link app. I have tried changing the audio output device, plugging in headphones, and searching through the settings on Steam with no luck. Audio works fine on the host and I can hear all sounds there, but they're not streamed through the app.

Any solutions?
