ASUS Xonar DS 

Q6: What is the most important benefit of the Xonar DS for musicians?
Answer:
1.  Ultimate Fidelity: Xonar DS has the highest quality of audio in/out for the 

cleanest sound production.

2.  Duplex HD: Supports audio sampling rates up to 24bit/192KHz for outputs 

and 24bit/96KHz for inputs.

3.  ASIO 2.0: Xonar DS includes an ASIO 2.0 driver for low-latency, low-

distortion music creation application.

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 sound card will always deliver 2 channel PCM data through the S/PDIF 

output port. For attaining 5.1 channel surround sounds, you can select DTS 

Interactive encoding output from the S/PDIF out menu, which will allow the Xonar 

DS to deliver upto 7.1 surround sound for games, DVD movies, and even stereo 

music.
Q8: Why can I hear and record sound from other recording devices when 

Answer:
Different from Windows XP, Vista has a multiple devices/streams concept in audio 

structure, in which the concept can be categorized into Digital Input and Analog 

Input. In other words, multiple recording devices can be used and working at the 

same time. In this case, Wave In or SPDIF-In, considered as a Digital Input, is 

an independent recording device from Analog Devices such as Mic In, Line In, 

or Aux In. Therefore, if you have analog inputs other than Wave In and set to be 

monitored, you are able to hear and even record sound from those analog devices 

even Wave In / SPDIF-In is selected as the default recording device. 
If you don’t want to hear the analog input sounds at that situation, simply turn off 

“monitoring” function on other analog input devices.
