SSD - Set Sound Device Current Version: v4 (2017-Sep-15) Windows XP allows you to output sound to more than one audio device... Vista and newer Windows versions do not. To overcome this "Failure by Design", (IMHO somehow related to DRM, preventing user to make digital copies of analog sources), I have coded SSD - Set Sound Device. SSD enables you to change the default Sound Device by shortcut or command line. It works fine on my Win10-1703 64bit machine. If you find bugs please let me know. The source and executable can be downloaded from my site: http://www.funk.eu Kudos to Ascend4nt and NerdFencer for parts of the code, and Yashied for his most excellent WinAPIEx UDF. Enjoy ...
