Question Problem with USB sound card dolby 5.1

[Soundman2]

Greetings!
I'm trying to let my Windows 10 PC emit a dolby 5.1 signal with the use of a Sweex USB sound card and a Pioneer VSX-C300 amplifier, but I can't figure out why it's not working.

So, the USB sound card is hooked up to the amplifier with the use of an optical cable and to my PC. The speakers are working fine, I tested them with a DVD-player and it gave me surround, but when I'm trying to play audio from the PC, it's only using the the frontspeakers and the subwoofer.

I have installed the USB Multichannel Audio Device software and when I test the setup with that, the left and right surround just comes from the two frontspeakers. I have also configured the USB Multichannel Audio Device in the PC sound options to play 5.1, but it just doesn't seem to listen.

Now I don't think there is a problem with the amplifier, since the surround worked with the dvd player on the same settings.
Might someone be able to help me with this issue?

Do you have 5.1 encoded audio on the PC? Have you tired the Dolby Atmos test files -- https://www.dolby.com/us/en/guide/dolby-atmos-trailers.html

in your sound device settings you should be able to turn on surround and test it
use Sound Control Panel, select your device and you can configure it from there.

is your usb capable of 5.1? nevermind, it is. in Sound Control Panel it should be your speakers you configure.

Little update.
So I released just yet that 1) the USB Sound Card is more than 10 years old by now and 2) that my PC actually doesn't even have a decent soundcard. These two things combined probably causes the bad audio I get. There is btw sound coming from the left and right surround speaker but it's kinda whack. So I decided to buy a decent sound card for my rig so I'll get a direct connection with the optical cable between PC and amplifier. Didn't order it yet but this just has to work I think.

So I'm looking for a sound card with an optical output supporting 5.1 and with a x1 PCI Express connection for the pc. My budget is around 50 euros. I'll be using it for gaming and music. Does anyone has a nice recommendation?

I'll open a new thread for this
