Hello. WavesMaxx software is dependent upon the version of Realtek audio driver, so if you do not get the WavesMaxx features you want with a certain version of Realtek, try a different version.
Go to the Inspiron 5559 html page to see all versions of the Realtek driver that Dell has released for that model. There are 4 for Win 10 (WT). Be sure to remove a newer Realtek driver before installing an older version.
1. Open the Device Manager (find it in the Control Panel, or type devmgmt.msc into the search box). 2. Expand the "Sound, Video & Game Controllers" section. 3. Right click on "Realtek High Definition Audio". 4. Click "uninstall." 5. Put a check mark in the option to delete the driver software, and then ok. 6. Restart the laptop. Because you removed the Realtek driver files, Windows will install its native audio driver, named "High Definition Audio Device". 7. Go back to the Device Manager and look for "High Definition Audio Device". If you see "Realtek High Definition Audio" again, that means that there was another version of the Realtek driver on your hard drive, and Windows found and installed it. So keep uninstalling & restarting until Realtek no longer appears under Sound...Controllers and "High Definition Audio Device" appears in its place.
When you have the "High Definition Audio Device" installed, you can install a Realtek driver over it.
