Since purchase (about a week ago) I may or may not get sound when firing up BF4. I've gone through http://answers.ea.com/t5/Battlefield-4/Info-Request-Sound-issues-after-latest-30-Jan-patch/td-p/2265... and http://answers.ea.com/t5/Battlefield-4/no-sound-at-all-in-Battlefield-4-PC/td-p/3318675 amongst just about every other thread available on the topic.
No matter what I use for output, headphones or 5.1, the end result is still the same. BF4 is the only game that gives this response, I have zero issues in any other games/videos/music etc. The only time the sound goes south is with this game.
I'm open for any thoughts/suggestions.
