Need Help Connecting 5.1 Speakers to Laptop

[MephalaFalls]

A family member gifted me Philips Multimedia Speaker 5.1 SPA8000B/94.

Here's the page for its specification: https/www.philips.co.in/c-p/SPA8000B_94/multimedia-speaker-5.1/specifications

You can refer to this to see the back panel: https/www.download.p4c.philips.com/files/s/spa8000b_94/spa8000b_94_dfu_aen.pdf

So the speaker has AUX and Bluetooth but ofc it doesn't play true 5.1 audio (there is however, a pro-logic mode). Is there any way I can play true 5.1 from my laptop? Laptop has a HDMI port and that's about it.

I'm sorry I am not good with the whole speaker connections thing. Help will be appreciated.

The manual, page 3
Use "DVD" inputs, and find a 5.1 USB sound card with analogue outpiuts, similar to this one. You'll need a couple of 3.5mm-to-RCA cables as well.
