How to set up a computer to use a dual sound system under Windows XP

The steps are as follows:

First of all, the following methods of setting up the two sound cards are used only in the case of Windows copy screen or extended screen. In the use of the second-part software (such as Aster or betwin) to do computer division behind the multiple sound card allocation method, is completely different, please read "Computer---A computer two".

In addition, the so-called sound card, the official saying is "audio device." In order to set the system to use a different sound card playback, or you can use multiple sound cards to play different music at the same time, you must first understand a concept, that is, the sound card and media Player (or any software with sound output), to give an image but not very accurate analogy, media players and sound card like Home DVD, CD player and speaker relationship, you can send a DVD or CD to any of the designated speakers, the speaker will be audible, and the two speakers are connected to the DVD and CD player, while playing DVDs and CDs can hear different voices.

And what does the audio "default device" in the "Sound and audio device" in the Windows Control Panel mean? As the name implies, "Default device" is when the software is not specified (or cannot be specified), Windows automatically specifies the "default device" for the software, and when we install multiple sound cards, The last installed sound card will automatically become the "Default device." However, this "default device" has a lower priority than the sound card that is already specified. So we can install a number of different players in a single computer, and then give them a different sound card, so that when running these different players at the same time, you can hear different sound on different sound card output. Software that does not specify (or cannot specify) sound card devices automatically chooses this "Default device".
