Good evening,
I'm having issues getting my 5.1 audio to play in full 5.1 instead of just stereo. At first, I thought it was the onboard RealTek audio device, but I have since purchased an additional PCIe 5.1 audio card and the symptom is the same.
After plugging in the speakers (green for front left/right, black for back left/right and orange for front/sub) and double-checking the drivers, I use the audio configuration wizard to set my speaker setup to 5.1, when it tests the speakers, all sounds (front L/R, back L/R, sub and front) come out of just the left/right speakers.
If I plug the orange input into the green jack on the soundcard, audio comes through the front/sub. If I plug black into the green jack, audio comes through rear left/right. But if I have the inputs into their correct jacks, Windows doesn't seem to be sending output to the other jacks.
As I said, at first I thought it was the card itself, so I got a new card, and got the same symptoms. Then I thought that, perhaps, the video card (that includes HDMI out for both video and audio) was interfering, so I swapped out a different video card, and the symptom persists.
I searched through the forums, and those whose issues looked similar, the suggested solution didn't work, or their issue was different from mine.
I don't think this is an audio source issue, because the Windows audio configuration test fails to output to the other speakers as well. I have attempted to download 5.1 audio samples, and it's the same with those, too.
Hoping there's someone who can assist.
