Cannot play after pausing tvOS (TVML/TVJS)

Question

I am developing a tvml/tvjs application and I have added the following code to allow audio to play in the background (applicationDidBecomeActive):

 let audioSession = AVAudioSession.sharedInstance()

 do {
     try audioSession.setCategory(AVAudioSessionCategoryPlayback)
     try audioSession.setActive(true)
 } catch {
     print("no audio to assign")
 }

I also set the first item in Required Background Modes in info.plist to App plays audio or streams audio/video using AirPlay.

My problem now is that although I can play audio in the background and pause the audio from anywhere in tvOS, I cannot play the audio after pausing. I am looking for the functionality like the Podcast app where I can freely play and pause the current streaming audio.

I cannot seem to find anything in the documentation for TVML/TVJS that points me in the right direction. Thanks!
