Shuttle aims to be a one stop shop for anything to do with managing & listening to your music. As the developer, I spend hours every day listening to music at my desk, on the commute to work and even as I go to sleep. I like to think I know what a music player needs to be and I do everything I can to put that into practice. Give it a try, you will not be disappointed.
This is a common problem, with an easy solution. Shuttle uses the Android Media Scanner to find your music. If you have any files starting with a “.” in the directories of your music, e.g. /sdcard/music/.nomedia, this tells the media scanner to skip this folder. You need to delete such files to allow the music to be found.
Please double check that the filetype you’re trying to send to the ChromeCast is supported. ChromeCast Supported Media Formats
Shuttle uses the native media player that comes with your phone, so as long as a filetype is supported by your phone, it is supported by Shuttle. Supported Media Formats
