I'm running windows 7 Ultimate x 64, have a brand new soundblaster Z 5.1 surround sound audio card.
Computer is a Gigabyte Z86 based mobo, Core i7 CPU, 16 Gb RAM.
When I run the speaker test feature in the software provided with the sound card, everything works fine. But when I play music (mp3) with any media player, I get no sound from the subwoofer. All the other channels work good.
I'm not running 5.1 computer speakers, with 4 separate amplifiers, (front, L+R, center/sub, rear L+R).
I think this is a software issue. Maybe something is not 5.1 compatable??
I'm going to try the optical out SPDIF from the sound card into an external decoder, but I have my doubts..
