I have 5.1 Creative Surround sound for my computer and I'm running them through the on board sound card. When looking at the playback devices and doing the test everything works:Front, Center, Rear, and Bass. When I play something else with sound (music movie etc.) only the Front speakers and the Bass work. Its odd that the bass works but the center speaker does nothing since they are on the same audio jack. Any suggestions on the problem/possible solutions?
Surround sound only works if the music or movie was actually recorded in 5.1 surround sound. If not then, the other speakers won't have sound coming out from them.
Try this, go into control panel and set Windows audio speaker to 5.1.
In the sound card's audio manager, also set that to 5.1
If that does not work, download the latest sound drivers.
If you got a realtek, then go to www.realtek.com.tw and download the HD Audio drivers.
Open up Realtek audio manager, head into speaker configuration and enable virtual surround.
