It CAN be configured, but you have to go hunting for the tools to do so.
I’ve got an old 5.1 surround sound speaker setup attached to my main rig, and in both Cinnamon and KDE (the only two I’ve tried), you can’t use the normal DE’s audio control panel to put the thing in 5.1 mode without first installing an old, probably unmaintained tool called ALSAJackRetask. Once you’ve retasked the jacks, several options for surround appear in the DE’s audio control panel. It knows but it can’t do.
