I have Dell XPS 15 9560 (Microsoft Windows 10 Home (x64), 10.0.18362) with installed Realtek Audio drivers 6.0.8809.1 and I have issue with maxxaudio software - it does not work  

When i try to change for example bass nothing happens - maybe its because there is only "internal speakers" option avaialable on output device select

 

 

I tried to reinstall audio drivers but it didn't help
