Well,i use a dual-boot system with Solus Budgie and old win7/64U for some time now and one
thing that growingly bothers me is that my ZXR sounds like a cheap onboard solution under Solus
while it sounds very good under Win,specificly when listening to music.
Probably its a thing that can be adjusted manualy,but i dont have a clue how to do that.
Any ideas ?

Hello, Windows has its own audio enhancement system built in - You can get the same effect with "PulseEffect" app. It's in the Solus Software Center.
