[No Sound???]

Thank you so much for the help! That did the trick and now I can hear my game again!

[No Sound???]

Soo.. recently I've had a bug with warframe. Whenever I turn on the game and I'm in my ship it's fine, but when I enter the Navigation system or any mission, there isn't any sound at all. It makes it really hard to enjoy the game. Anyone know how I can fix this?
