Self reference, and also a heads up for those people looking into listening to 5.1 surround sound in Far Cry 4 and Watchdogs which usually play no sound when Dolby Digital is enabled.

This was tested and works in my configuration using a Sound Blaster USB Surround Pro X-Fi, and doesn’t involve any patch or hack, but a simple linear procedure; the first step is to download the latest drivers from Creative website (may ’14), and then, as the good sir melgu said on steamcommunity:

• Open Creative Entertainment Console
• Click on the Dolby Digital Live icon
• Check the second box (a warning will appear, read it to undestand what it does, then accept clicking Yes)
• Open Change Sound Card Settings from Windows Start Menu, and set the entry Speaker (Sound Blaster blahblah) as the default peripheral
• Test your games
