Experiments need to use a notebook to control four speakers, at a time, one of the speakers a mono sound; At another time, another speakers another mono sound, a sound card for notebook integration, another plan to buy USB sound card, now I compiled program can realize with the integrated sound card, according to the experimental requirements for the voices of random playback experiments, excuse me: 1, how to use c + + builder programming, real-time switch sound card? 2, the presence of the routine? 3, please recommend a high quality USB sound card, for frequency response is good, thank you!

CodePudding user response:

Haven't played, theoretically other languages to achieve a c + + builder can be achieved

What interface do you use? WDM?

Is right, WDM, could you tell me how to implement? Have a routine?
