Skins sometimes have a different way of kicking off artist slideshow (or enabling it).  I'd be happy to look at a debug log (with Kodi and AS debug logging on), but if it's only happening with Transparency! you might check in the support thread for that skin.

The Transparency forum didn't offer any solution to the problem. I looked at the AS Wiki and there's this instruction:

"If you want to manually add support for AS to an existing skin, you need to add/update a few things in MusicVisualization.xml.
To run the script:
<onload>RunScript(script.artistslideshow)</onload>"

My questions are these:

Which MusicVisualization.xml (What is the path?)
Do I need add this line to the script or edit a pre-existing line?

That file is in the skin folder, which is in your userdata/addons directory. Where that is depends a bit on your platform.  I can't say whether you have to add the line or edit an existing one, since that depends on if the skin already has an onload section.

If it doesn't have the line, would the line go at the beginning?
