Upmix stereo to 5.1 (WARNING-- Read)

One of the things that bothered me about using this App (or Popcorn) instead of downloading the torrent and playing it with VLC, is that stereo isn't upmixed to 5.1..

After a bit of research I found this page: https://code.google.com/p/chromium/issues/detail?id=355435, which talks about the same issue in Google Chrome. They recommend enabling --try-supported-channel-layouts, but warns about possible crashes to some users.

"Sadly this feature causes crashes for many users so we had to disable it by default."

For me, it made wonders. I can finally enjoy watching movies/series in 5.1.
I think we should test it.. may be the conditions that cause this to "crash for many users" aren't here.
