I’m using a Realtek sound chip in a Mac Pro 2008 with Windows 11.
There doesn’t seem to be support for 5.1 sound using SP/DIF. I have a Logitech X-540 and a Technics Digital SH-AC500D Surround Sound Processor, both which I got for free. The Technics is an antiquated obsolete piece of technology that was probably replaced by a 5c chip on a $15 Wal-mart DVD player a decade ago, but it’s free and it’s what I have. Lacking an optical port on my Logitech speakers, and the requisite number of analog jacks on the Mac Pro, I am able to at least play back Dolby Pro Logic using the Technics hooked up the Mac, and then the speakers to the Technics.
I also have a Syba USB sound card/headphone amp with optical and coax digital out, sadly, it’s 2.1 only.
Is there a way to output 5.1 OS wide in Windows?
I can buy a brand new USB 5.1 sound card for not much money, but reusing old junk that nobody else wants is kind of a passion of mine, and this is for my workshop where I have all kinds of frankenprojects on the go, so it would fit in just fine.

IIRC the feature is Dolby Digital Live or DTS Connect.
I think support is going to come down to the drivers for your sound device, I believe there were extra licensing costs for doing the DDL/DTS 5.1 output.

edit: if you want to attempt to pass real time sound (not prefabbed movie/tv surround sound) via Toslink/SPDIF, you’ll need what Cool Modine suggested, although those features were End of Life over 10 years ago.
Keeping the Technics around is not worth the hassle of that, not ever. If you’re stuck on analog for the sake of those speakers, accept it, and get the sound card.
Dolby Pro Logic
Click to expand…
Dolby Pro Logic is a stereo signal so this isn’t shocking. Actual DPL hooks (aka analog metadata*) are quite rare now so all it’s probably doing is upsampling in a very archaic way. Which is fine and probably good enough. But just be aware that the entire chain is stereo.
* If you listen to some CDs from the mid 90s (or mp3s ripped from them, even) they have some crazy surround effects due to DPL hooks being built in, effects that aren’t going into modern digital releases

Windows can do anything it wants when it comes to sound but it’s probably not going to let you shoot yourself in the foot by feeding a DAC something it says it can’t handle.
Maybe you’ll find someone who has hacked a driver to allow that but I’ve never dived into such waters. I’d just go ahead and get the sound card and skip the Technics box.

AFAICT, those apps are actually just spacial-mixers for headphones (primarily) and not the middleware above.
DDL and Connect grew out of a niche first started by the Nforce motherboards
That put Xbox style sound chips on boards to provide digital-surround out for «high end consumers.»
The very second HDMI became available (there was at one point, for about six months, audio cards that had HDMI out!*), supposed high end consumers no longer needed a digital route and thus the entire market collapsed back to analog for people with Logitech speakers like the OPs.
There were people like me who refused to get AV receivers (for HDMI/Display Port sound) because we had Home Theater in a Box type units, a step up from Logitech (so we had convinced ourselves we were a high end market who deserved consideration ), who chased after DDL/DTS Connect cards and drivers for a period of about 8 years, but eventually the tech became too deprecated to even worry about, even for us holdouts.

Ha, cool, I have two motherboards with nForce, one is a Shuttle PC, the other is an Asus motherboard.
One is AMD Athlon XP, the other is Athlon X2, I believe. I never knew that was a unique feature for that chipset, though I do know they touted sound capabilities all over their marketing. Neat that it started life on the Xbox, which makes a lot of sense.
Looks like you can enable DDL and DTS Connect on any Realtek card/chip with a hacky patch to standard drivers. However, this requires disabling mandatory driver signing (obviously, since you are running hacked drivers).
I can’t disable driver signing without booting into the recovery menu, and I can’t do that in my Mac without changing the graphics card, since you need a special Mac graphics card to get video during the EFI. I might pull the SSD, and do the install on a normal PC. But I don’t know if it’s worth it though to run unsigned drivers.
This machine isn’t really use for anything other than 3D printing software (Cura, OpenSCAD), but I thought I could put a beefier GPU in it and use it as a spare gaming PC, since the CPU performance is comparable to my Zen 3 APU in multicore.
I’ve never really played games before with discrete surround sound (only Aureal A3D with headphones), and the only real surround sound experience I have at home is with my Sonos setup. But that uses a soundbar up front, so not real surround. The rear surround effect is pretty amazing during movies, but up front is kind of underwhelming. The Logitech speakers would be a lot closer position, so I figured this would be a cool thing to try.
Not worth it, I suppose.
I have my eye on a nice StarTech sound card which seems to be pretty good, as everything from StarTech tends to be. And very competitive pricing, considering the brand.

Optical out is only 2.1 channels though, so even if I wanted to play around with the Technics, I’d still be where I am now.

ok I guess I’m fundamentally misunderstanding how this works.
If you connect your PC to a TV via HDMI and connect the TV to a Dolby receiver via optical you can play a movie in VLC and get proper 5.1 audio. I thus assumed things like DDL were basically a virtual 5.1 sound card that does the Dolby encoding and passes the stream on to the hardware driver the same way VLC does.
I don’t see why the hardware or its driver would need special support for a realtime stream when it already supports playing it from sources like media players. I must be missing something.
Coincidentally I’ve been thinking about this lately because I have a flight simulator rig with TV and a cheap 2.1 analog setup and was wanting to use a spare receiver connected to the TV via optical to get 5.1. It’s crazy this isn’t supported out of the box with Windows, let alone even with addon software!

Because most TVs won’t do what you describe.
They will only output 2 channel PCM over the optical output precisely because they need special licensing and possibly hardware to take a certain audio signal from an HDMI input and convert it to a compressed format that will work over TOSLINK like Dolby Digital or DTS. So if the source material has a 2 channel audio track, you get that passed through to the receiver over TOSLINK or you might get a 2 channel downmix from the 5.1 or 7.1 source material, or you might just get 2 of the channels from the 5.1 channel source material and that means you miss out on 70% of the audio of the original content like voices and stuff that are mainly in the center channel and don’t get passed through without a downmix.
The problem for computers that don’t support HDMI out (uncompressed multichannel audio from like HDMI 1.2 or later, I think) is that you either have to have the right combo of outputs (TOSLINK or SPDIF Coax digital), the right hardware and the right drivers and licensing for the computer to either output an original pre-encoded 5.
1 channel mix from source material (like playing a DVD) or you have to have the right hardware and software (drivers and licensing) for things like games to send their audio into a real time encoder that takes their multichannel audio and compresses it for output as Dolby Digital Live or DTS Connect.
The alternative to that is those motherboards that simply had 6 or more analog outputs for multiple channel audio out, like Center, FR, FL, RR, RL and subwoofer maybe. Then a game could send sound directly to those channels without re-encoding it for the limited bandwidth that SPDIF supported and DVD audio could be decoded on the computer and output through those analog outputs.

Surround sound in games is awesome. Stand by a waterfall in Skyrim in 3rd person view and rotate the camera around you and the water will sweep the outside of your room; arrows will fly by you and clink behind you, etc. It’s worth it, just not worth screwing yourself over with kludgy hacked drivers that create a lossy-compressed sounds when they even work. An AV receiver with Dolby Atmos can even take a game that only has stereo sound and upsample it to surround sound much better than the antique Dolby Pro Logic can do.
Optical out is only 2.
1 channels though, so even if I wanted to play around with the Technics, I’d still be where I am now.
Click to expand…
Optical out is only ever 2 uncompressed channels. There’s nothing that can send more than that so maybe you’ve been misreading the specs on all of this: when a DVD sends a 5.1 signal over Optical, it’s sending a compartmentalized lossy signal which is why the DDL/DTSConnect was such a processor intensive thing back in the day (and an expensive feature) as it was basically creating 5 MP3 files simultaneously at a time when people had to wait for MP3s to be made all patient like! I still wouldn’t try reliving the DDL experience in 2022 though. Go analog for this project.
I don’t see why the hardware or its driver would need special support for a realtime stream when it already supports playing it from sources like media players. I must be missing something.
Click to expand…
You’ve got that backwards: the digital-analog-converter doesn’t care whether the signal its getting is realtime or prebaked, so long as it fits an antiquated lossy standard perfectly. Outputting to that standard perfectly requires a lot of conditions to be met.
In fact, if you hook up a PC to a TV + Optical Receiver like you said, the sound only passes through because HD Master Audio and DD Plus often contain backwards compatible lossy streams for «scrub-level» hardware inside them. Without that, however, your computer would only be able to downsample an uncompressed True HD audio track from stereo down to stereo…
Yes, everything has the processing power to do DDL at this point but that’s like having a gas station sell leaded gasoline: there are just a few nerds on shoestring budgets who could take advantage of it, so given the various IP licenses at play, no one bothers, which is why it’s now in the realm of hacked drivers.
cheap 2.1 analog setup and was wanting to use a spare receiver connected to the TV via optical to get 5.1. It’s crazy this isn’t supported out of the box with Windows, let alone even with addon software!

It was supported. In 2005. Now they expect you to use modern hardware (is your monitor connected via VGA?). The problem is that audio devices tend to outlive audio standards by multiple generations. But using HDMI you can output 5.2.4 sound if you want (5 surround channels, 2 subs, 4 height channels), which would make one hell of a cockpit.

@Paladin@richleader Thanks for explaining, I get it now.
I thought optical could support 5.1 but good to know it cannot without degradation.
So now I have two problems lol… For my main home theater setup I use a receiver that supports HDMI but not 4k HDR. To get around this I got a 18Gb capable HDMI switcher that has optical out so I use that to pass audio to my receiver. The receiver detects 5.1 and it sounds great but from what I’m reading here I’m actually getting degraded audio. Damn! I was wondering why the Dolby light doesn’t come on when I use it, I guess that explains it.
That receiver has multichannel inputs (ie 6 analog inputs) which is ideal for the PC so it sounds like the solution to both of my issues is to move that receiver to the cockpit and connect it to the PC via the 6 analog outputs (or HDMI?) and buy a new 4k receiver for the home theater.
That’s much more expensive than I was hoping for

My TV is connected via HDMI but the TV doesn’t have HDMI passthrough so I was thinking optical. But since that’s no good maybe I can use my video card’s other HDMI output to go to the receiver. I thought Dolby or something was required for but if not then that’s probably my solution right there, thanks!
And if you think that would make it one hell of a cockpit you should see the motion platform and peripherals
edit: connecting the receiver to the other HDMI out works, thanks for the tip!

Awesome. On mine, I needed something called an EDID emulator to fool it into thinking it had a display. They used to be expensive but now they’re like $12 for a three pack.
