Q3: Why do I need Dolby for PC games?
Answer:
1. Dolby Digital and Pro-Logic IIx are available on the latest game consoles,
like XBOX360, PS3, and Wii. Dolby can provide the best gaming sound
experience and compatibility with home theater or TV systems.
2. Dolby Headphone and Dolby Virtual Speaker are the best 3D sound
positioning, spatial modeling and 5.1-channel virtualization technology for
regular stereo headphones and speakers.
Q4: Will PCM sound output through S/PDIF be just 2 channels even with
different analog output channels?
Answer:
The S/PDIF protocol specification (IEC-60958) can only carry 2-channel PCM
data or non-PCM AC3/DTS data. So, when a user selects PCM output for S/PDIF,
the Xonar U1 will always deliver 2 channel PCM data through the S/PDIF output
port. For attaining 5.1 channel surround sounds, you can select Dolby Digital
Live encoding output from the S/PDIF out menu, which will allow the Xonar U1 to
deliver 5.1 surround sound for games, DVD movies, and even stereo music.
