This plugin (Solo Music Player) has two (2) settings which include Title Bar Text - Title Bar Text Alignment and one (1) Audio Format input field. Also included are the Play - Pause - Volume Up and Volume Down buttons.
To test your Audio Format URL file, just copy/paste it directly into your browsers address bar and hit enter. If you don't hear anything, then your Audio Format file is not supported.
Note: this plugin would be great for adding audio sound during the seasonal holidays.
