Force setting the audio output device

[Romantic-LiXuefeng]

In the application scene, When I'm playing the movie with ExoPlayer on Phone, normally the sound output through the speaker. When a headphone is plugged into the jack, the sound directly to the headphone. I hope even if a headphone is plugged into the jack, I still need to force output through the phone speaker. At the same time, I want to use the headphone to communicate with other guys. Is there any way to implement this?

Media Routing supports changing the output device, but I believe speaker and wired headphones are considered the same device, so your use-case doesn't seem supported.

They are other ways to control the audio routing but are either system APIs or too crude to support your use-case (eg: setSpeakerphoneOn).

Closing as this is not related to ExoPlayer but media routing APIs in general.
