No sound in subwoofer when using mediamonkey, vlc, netflix

[michael1994]

I setup a subwoofer to run from the pc from the orange hole to the sub via a 3.5mm to rca cable. I can't get it to play sound from any other program other than pandora, battlefield and youtube. VLC, netflix, mediamonkey all ignore the sub and don't use it. My speakers are connected to the computer through the green hole to the t amp (no sub out on the amp). I tried downloading my audio drivers but I get an error saying "can't find hd audio device". My motherboard is a gigabyte gaz77xd3h running on the latest f18i bios. When i was on 7 the drivers worked fine, but on 8.1 they don't install. I've tried the original version that came with the mobo and the most recent one and both don't work.

You apparently are trying to circumvent the speaker setup with the separate bass speaker. Audio systems are set up to feed audio based on how you have your speakers set up (e.g. 2.1 stereo , 5.1, etc). As you apparently have a 2.1 (or 2.0) speakers connected to the green speaker jack, what do you have the speaker type set as?

In multiple speaker setups such as a 4.1, 5.1, 7.1, etc although there are separate connections to the speaker jacks, its really controlled internally in the speaker system, not separate like you want to do it. What you are doing may work with some functions but its not the correct/legitimate setup.
