I try to use the VAC create virtual sound card, put the system sounds in VAC and then output to the microphone, but the VAC can not do enter to choose the sound card output

CodePudding user response:

I think it will lead to a positive feedback effect, called is take microphone close to the speakers, produce the noise,
Input to output, then the output as input,
Unless caused by the microphone sound playing is not sound system, but another system of wheat
