Upscale 2-channel audio for 5.1 speakers in Windows 10?

[itm2]

I run Windows 10 on a B450 Aorus Elite motherboard, and am using the on-board Realtek sound card. I also have a 5.1 speaker system (Cambridge Soundworks DTT2200). I'd like to upscale my stereo music so that it plays from all of the speakers. Does anyone know of a way of doing this?

Thanks for that - I've installed Equaliser APO and following the instructions at that link for configuring it, but can only get stereo playback from the front speakers when I select "5.1" or "5.1 Surround" from the Channel configuration in Equaliser APO. I've posted a question in that thread - hopefully I've missed something simple....

OK I think I've found an alternative solution. I discovered and installed a Windows app called Realtek Audio Console. If I set the Speaker Configuration in this app to "5.1 Speaker" and turn on the "Speaker Fill" option I get stereo audio routed through all 5.1 channels :0)

If some one else arrives here, like me. FYI i use voicemeter with the 8x8 gain matrix

My upscaling method - which took some time in tinkering, tweaking and optimising, has now become much more powerful than simple staightforward 'upscaling' per se as it involves the usage of a few VST plugins, one of which is Halo Upmix by Nugen.
The tools I used are not freely availabe but the end resault to my ear sounds far superior to anything I tried before. It enables total control over systemwide audio at the cost of relatively low and acceptable latency (~11ms) using standard Windows DirectSound (KS) as backend as opposed to something like ASIO or even WASAPI.
