How to output 5.1 sound in Windows 10?

Question

Audio

There is an Asus Xonar SE 5.1 ​​(PCIe) audio card, a Windows 10 computer, 2.0 speakers and an active subwoofer.
I connect speakers to the line-out socket of the card, and a sub to the sub output of the card. The latest firewood from Asus is standing, the settings are all for 5.1.
I start music from the browser - the sound is only in the columns (the sub is silent). I start the game - the sound is only in the columns (the sub is silent). I start music with Aimp - the sound is everywhere.
Question: how to bring sound from everywhere to speakers and subwoofer?
