Please make sure to update PhotoTV to version 1.9.25 to benefit from all features (Roku Home Screen → Settings → System → System Update → Check now).
Supported sources are Dropbox, Google Drive, OneDrive and USB. In order to play music with the slideshow, you will need to do the following:
• Link the folder that contains the songs under your source.
• Once the folder is linked, open it and change its media type to ‘Music’ or ‘Images & Music’. That is it, launch the slideshow and the music will play with it.
Music transition defaults to random, it can be changed to sequential from PhotoTV Settings → Music. Under the same section, there is an option to show/hide song names.
• Same as image folders, music folders and their sources have to be enabled in order to fetch their music.
• Screensavers cannot play music and therefore the option to play music will be ignored while running PhotoTV as a screensaver.
