No sound when casting screen
When I use the "Cast screen" on my Nexus 7, and selects a video (not Youtube), it always displays video, but mostly there is no sound. Sometimes the sound works, but I have not been able to figure out why/when the sound is also working. Occasionally after having rebooted my N7, restarted apps etc., the sound might suddenly work again.
The situation is identical on two separate setups (different networks with different chromecasts), where the only thing in common is my N7
