0.2.11 - Sound and controller issue

[tulang3587]

I was using 2.10 previously, but today for some reason it always crashes when I try to send the link to a friend. Then trying 2.11, it doesn't crash, but has some problems.

1. When the friend accepts the remote play link, the "Steam Streaming Speakers" is always set to default device, causing no sound to play on my end
2. The controllers seem to be given to desktop as well, so my friend inadvertently moves my mouse around
