I was able to add the AdvancedSettings.xml file to my secondary system, which consists of Kodi 21 on a Windows 10 PC. I also added the music video MKV files and CUE files as a source for Music. For the most part, it works, but there are some quirks. Clicking on a song in an album starts the video player, but it's in the background, and I have to click somewhere on the screen to bring the video to the foreground. Maybe there's a setting I have to change.
In the default Estuary skin, there are no Skip buttons on the player, only fast forward or rewind. Aeon Nox Silvo does have the Skip buttons. When I changed back to Estuary, I found I could access a Skip forward button by going to the left panel.
The only other Music source I've added to this system are my Atmos albums, which contain the songs as M4A files. I could have sworn that I was play these from the Albums menu before, as I can on my primary system with a Vero 4K+, but now, when I click on a song in an Atmos album, Kodi just cycles through the songs on the menu and never plays anything. I have to go to the Files menu, open the album folder, and click on a song to get it started.
