The short is. I have 2 sound devices Creative SB X-Fi Analog and Creative SB X-Fi Digital
I have Winamp set to the Analog and pass this to my Denon amp and this is used exclusively for this.
All other audio is passed via the digital stream into my 5.1 home theater. This is set as my Default Audio Device in Windows 7.
Now my problem is when i select Dolby Digital Live via my Encoder tab inside X-Fi Creative it will, rather than playing all audio passing through my Creative SB X-Fi Digital, play all the audio from my Creative SB X-Fi Analog. This means i can't play my games in 5.1 Dolby as is desired.
Interestingly though when i click on the Dolby Digital Live settings it gives me a select box, which only shows Sony 5.1 and then tells me
To enjoy Dolby Digital Live, ensure that you select this playback device: Denon (creative SB X-Fi)
So i want this playback device to be my default.
