I just reinstalled win 10 and i'm getting no sound from 3 speakers and my subwoofer. Windows and the Realtek Audio Manager both say there's an output but i hear no sound from anything other than my front left and right. Both are set to 5.1 but neither test will output 5.1 sound, just stereo. From what I've read there's not a speaker fill option, at least not one i see. I've turned on DTS connect, did nothing. And I've tried almost every option ASUS Supreme FX's sonic studio will give me, no dice.

The Realtek sensors are saying the wires are connected properly but there was something of note. I did try to take out the black and orange wires to test if they were an issue. I noticed that while the sensors no longer picked up those connections I still had the options for quad, 5.1 and 7.1 still there in both windows and realtek. From what i read that shouldn't be possible but I may be mistaken with that.

If there's any more info I can provide I will but so far that's all I've been able to figure out and I still can't get the sound to play out of either my sub, center, or rear speakers.

If the sound card supports 7.1, that and the lesser options will still be shown regardless of which speakers are actually plugged in. Those configuration options show you what the sound card supports so why wouldn't they be shown all the time?

Maybe one or more of your speakers have gone south.
Test them on another 7.1 audio PC if possible, to eliminate that possibility.

I've been switching these speakers in my sub connection ports for a while now to test them. They all work fine. I can't even say the sub is bad if the connections through it work fine.

Ah I didn't know that. When I was using win7 a while back it wouldn't let me choose 5.1 or 7.1 if I didn't have all the connections right.

Ok, so apparently there's no problem with my speakers. My speakers work but 5.1 surround won't test through either windows or realtek. I get no error messages but I do get sound with audio tests for only 5.1 formats (ac3 and mkv, maybe more). As far as i can tell windows and realtek acknowledge that the speakers are there. Is there no way to make win10 use the whole system for everything?
