I’m trying to play the audio track that accompanies my video through the built-in speakers in my display. I’m using ciWMFVideoPlayer on msw10

I’ve tried changing the following lines:

```
//mTestVideo.loadMovie(videoPath, "Headphones (High Definition Audio Device)");
mTestVideo.loadMovie(videoPath, "HDMI (High-Definition Multimedia Interface)");

```

but to no avail… There’s no documentation RE the source URL so I took a shot in the dark. Anyone managed to get this to work?

Hi @Craigson, it should list out the available audio devices. See [here](https://github.com/stimulant/Cinder-WMFVideo/blob/master/src/ciWMFVideoPlayerUtils.cpp#L1035). You can use that string as audio source. This needs to be cleaned up and made its own method or something.

You can get the audio device names with `ci::audio::Device::getOutputDevices()`. This has worked for me.

```
deviceName = "HDMI";
for (auto audioDevice : ci::audio::Device::getOutputDevices() ) {
	ci::app::console() << "Output device " << audioDevice->getName() << std::endl;
	std::size_t found = audioDevice->getName().find(deviceName);
	if (found != std::string::npos) {
		mAudioOutDevice = audioDevice->getName();
		ci::app::console() << "MAtched device " << audioDevice->getName() << std::endl;
	}
};
//and then
mMoviePlayer.loadMovie("thVideo.mp4", mAudioOutDevice);

```

But be aware that the devices name list might show the same device twice, one time as input and the other as output.

Thanks that worked a treat. Never worked with the audio API before, should’ve known better and looked there first!j
