title: Switching Audiotrack on Chromecast
body: <p>I actually cannot believe I couldn't find an answer to this as it appears to me as if it should be a common problem - am I using the wrong terminology?</p>
  
  <p>However, I am looking for a way to switch the audiotrack of the video that is being sent to be played on chromecast. More precisely I'm talking about a multitrack video File embedding two audio lines (mkv-format).</p>
  
  <p>I've not found any possibility to do this using the (Android) SDK, nor could I change it using JavaScript on the Receiver App itself. (This would at least enable me to implement the ability using a custom receiver).</p>
  
  <p>From my research I found, that the video element is supposed to get a audioTracks and videoTracks attribute but accordingly it is not yet implemented by any browser and thus obviously not available on chromecast.

  <p>Any suggestions?</p>
