This is driving me insane. All of the supported apps for Chromecast are working with my PC/Phone: Netflix, Youtube, etc. However, when I try casting a tab, audio does not work, just video. When I drag local videos or songs into the Chrome browser, the audio works for those. However, normal websites do not play audio. I actually got the Google Music website to play audio by enabling HTML5 audio in the labs section. However, this is the only website I have gotten sound to successfully cast on. Is there someway to enable HTML 5 audio everywhere in Chrome? I've tried different computers, TVs, power sources, and a factory reset with no luck. What do you guys think is wrong? Any help would be appreciated!
