Dolby without HDMI?

I have a PC with a cheap sound card that supports 5.1 surround sound.

It fits my 7.1 amplifier well and I can already play surround minecraft with it. So everything works.

I installed the Dolby Access program. Setting up a home theater is free, but Dolby Access writes:

This device is not compatible with surround sound.

The instructions in the program state that you have to connect all surround devices with HDMI. This is not true, because surround can also be connected with 3 jack connections or 6 chinch connections.

Is there another surround app that can handle analog signals?

I installed Voicemeeter Potato on my PC, but this program has no LFO for the sub.

Can anyone help me?

Dolby Atmos on PC is only designed for 2.0 and 2.1 channels. That's what it's meant for; Surround experience on 2.0 or 2.1 channel hardware (at least on the PC).

In the past, AV receivers had the 5.1 component input as an alternative to "Digital Cinch" or "TOSLink" (fiber optic).

My Teufel Concept E 5.1 is also fed with such analog signals (3x jack).

And I also connected my old Pioneer DVD player via analog 5.1 (cinch), because only then could the sound of SACD and DVD-Audio be transmitted in full quality. (Bluray was far from there…)

In order to have a real surround sound signal in Dolby Digital or DTS output from a normal sound card, the sound source has to be delivered prefabricated.

Only the better sound cards are able to generate such a compressed audio signal from several individual channels in real time and without latency.

And this is always done using hardware on the sound card and can't be simulated using software. At least I don't know of any such real-time encoder drivers.

Only a 2-channel stereo or a (Dolby / Virtual) surround signal is also possible in games via the HDMI connection. Without the right sound hardware, there's no real surround signal here either.

So you need a better sound card that can generate such a signal live.

Only then can a real surround sound signal be generated and output via HDMI, glass fiber or digital cinch.

For example, Is the Creative Soundblaster Z ideally suited for this (5.1 & 7.1).

The somewhat cheaper "Soundblaster Audigy Rx" unfortunately can't do this…

I don't care about latency… The only thing I really need is an LFO for the sub…

Is there an app for that?

You can also choose "home theater". This program only supports HDMI…

If only stereo (2.0) is supplied on the sound card (physically), how should the bass track be separated from it?

If you can't set a crossover frequency for the sub-output on your 7.1 receiver, you've been unlucky… Although I can't really imagine anything like that.

You only get separate signals from the sound card via the analog 3x jack that you already mentioned. But you can no longer do anything with the newer AV receivers because these inputs have mostly been omitted.

There are also apparently various attempts at a software real-time AC3 encoder, but this is probably quite freaky to use, unstable in operation and not entirely free of charge.

But there's also reference to sound cards with this "Dolby Digital Live". Only the Creative "X-Fi" sound cards mentioned there are significantly more expensive than these "Soundblaster Z".
