Have the same issue, even after changing the default to the speakers there's still no sound, also have tried headphones and still no sound, I can see the level bars lighting up though. very frustrating .Your driver has set by default your internal speaker as main peripheral.
And the reason why when you plug it to the front jack it does work, it's because it has priority over the jack behind (all drivers, or most of them work that way).
To do this you got to go in your Audio advanced settings, and change the peripheral by default to your external speak, you must know its name to choose the good one.
Good Luck
Thanks, I have tried all that. I should mention that the sound from the external devices disappeared after fresh Win 8.1 re-install, before that it was fine.View attachment 32363
