I've posted this previously on another post, but for me I have to install Equalizer APO. ( the other post specified my specific configuration, it takes a bit more than simply installing it to ensure it is working ) some trial and error might be required.
you can use the configuration editor to add a preamp to ensure it's working.
For the arctis 7 usb headset ( amongst others) that have their own quasi surround sound, this is the only method to fix this for me.
Even for this particular headset, disabling the 7.1 surround option, and setting it to 2.1 in windows has no effect.
A past version of their steel series software did not have this issue. I could set a profile to disable their surround setting for specific exe, but past a certain update, it stopped working, and uninstalling their software all together had no effect ( i suppose maybe it did something firmware wise on the headset, but who knows )
At any rate, there are some pretty nice addons for this software, PEACE GUI. there is also a 7.1 surround add-on called Hesuvi and with some tinkering you can switch back and forth from 2.1 to 7.1 profiles, but that is a lot more advanced and has it's own issues.
hopefully this helps.
