Dolby 7.1 Nanonymous No.8369 [D][S][L][A][C]
Can I split the channels of a dolby 7.1 mainboard into stereo channels.
Jews want twice the money for 5.1 so I thought I could just split the fucking channels and have the same effect.
To be more specific: I want to have 2 times stereo from a 7.1 device, so I can connect to stereo speaker pairs.
To me it seems like they're trying to force me into buying their 7.1 certified jew crap instead of connecting anything I want to connect.
Or maybe I can output quad over 7.1 and split that with some sort of cable if that exists?
Has anyone tried?

I also want to avoid additional devices.

I don’t into audio enough, sorry.
Wtf is Dolby and what does it actually do?
Might be a starting point.

I'm pretty sure you want to avoid adding sound from surrounding channels to those 2 basic channels in front. In fact, you don't have to do that. If you don't have surrounding speakers in your sound system, you just can listen to whatever number of channels on your 2.0 (stereo) system. The rest of the channels will be mute and therefore kinda wasted, but it doesn't matter if you don't have the surrounding channels. As for the reason why you don't want it, well, the sounds from the channels BEHIND you were actually designed and recorded to sound from behind. Just stick with your stereo setup, it's good enough if you don't have a home theatre.

Nanonymous No.8399 [D] >>8402
NO. I have 5.1 and stereo speakers in the green slot and in another pair attached to the black slot (rear speakers).
But 7.1 doesn't have 6 slots but just the usual 3. It works through having multiple channels through one slot.

>Wtf is Dolby
Dolby standardises audio output.
>what does it actually do?
You know there is more than stereo, right?
Even old video games from 2005 have surround sound for more speakers, subwoofers and the like.

Nanonymous No.8402 [D]

Are you OP?
Then you have to figure out which slot corresponds to what group of channels (shouldn't be hard at all), then which wire responds to which channel (it's either in the docs or you will have to cut your wires open and add new wires and connectors, or, well, cutting wires open isn't strictly necessary, maybe there are some "splitters" for this kind of shit), then figure out which channels you don't want, since you will have 2 extra (it could be rather important since I dunno how 5.1 vs 7.1 speakers are supposed to sit).
Or you could just get another stereo pair similar to what you have and add it to your sound system LOL. Just research this shit on Wikipedia at least. I mean, speaker angles, where they are situated, how 5.1 source is played on 7.1 system and vice versa. I legit don't know much about surrounding sound because it's absolutely useless in piss poor apartment I have.

Nanonymous No.8403 [D] >>8406
Okay maybe I am the one who is confused.
Why does it say 7.1 on some with 3 jacks and on some with 6 jacks?

Nanonymous No.8404 [D]
Yes I'm OP but cables are all the same.
Maybe I'm the stupid one getting confused by the number when I should actually be looking at the amount of jacks.

Nanonymous No.8405 [D] >>8407 >>8408 >>8411
Okay to make it more clear:

Both of these are 7.1 but one only has 3 audio jacks. What does that mean?
Anyone here who can explain that shit?

Nanonymous No.8406 [D]
>>8403
I dunno what you're talking about.
Though the simple indicator that a jack has more than 2 channels on it is that it has more than 3 contact areas, obviously. Though I don't know how real they are, I usually face more than 3-contact jacks when they are used for something like headphones with a mic.
If you don't have anything like that, then your sound card or whatever has to have 4 line outputs or something (1+2+2+2). Combined with possible mic and other inputs and headphone outputs, your sound card could have 7 jack holes. Yikes.

OK, it is S/PDIF. Forget what I said about messing with wires.
>The ALC887 is a 7.1 Channel High Definition Audio Codec with two independent SPDIF outputs
I think it works by connecting S/PDIF to an amplifying device that supports it, and then the device manages the channels, probably passive speakers.
If your sound system relies on jacks to the sound card and has active speakers, you probably don't want that new system. Though if you happen to HAVE a home theater amplifier, you're probably OK.

That Gigabyte mobo seems to have a regular 5.1 output though.

Nanonymous No.8410 [D] >>8412
There is no S/PDIF on either of those mobos.

Nanonymous No.8411 [D]
>>8405
Though I really don't understand this in its entirety.
Looking at the datasheets for two repspective audio devices-

http://www.hardwaresecrets.com/datasheets/ALC887.pdf
http://www.hardwaresecrets.com/datasheets/ALC892-CG_DataSheet_1.3.pdf

-I see all the channels (center, front, surround, sidesurround) on the block diagram. That probably means the device could provide you with all the jack holes but the mobo designers decided not to implement it, leaving S/PDIF as the only option.

Nanonymous No.8412 [D] >>8413
>>8410
I dunno. Specs say the second one supports it.

https://asrock.com/MB/AMD/A320M-DVS%20R3.0/index.asp#Specification
https://www.gigabyte.com/Motherboard/B450-AORUS-M-rev-10/sp#sp

Maybe you have to read manuals for them at this point.

Nanonymous No.8413 [D] >>8414
>>8412
Definitely read the manuals. The mobos pics have some pinouts on them with a suspiciously big amount of pins on them for it to be a beep speaker.
OK I wasted enough time learning about this shit. It was interesting enough.

Nanonymous No.8414 [D]
>>8413
I mean those pinouts are marked as "audio" or "speaker" as well.
