I created a category and uploaded 8, 16, 32, and 48 hz versions of the file. I can select the category on a ring group or queue, but my custom music does not play. It just plays the default one. I've tried restarting the module per documentation but that did on work either. Watching fs_cli, looks like an attempt is made to play it (not sure if it's an attempt, at the very least i see the reference to the name of the category and 8hz,) but I don't see errors and it always plays the default.
