Transmission of the two audio stream in a simultaneous way.

[GianDragon]

Hello,

I was doing some experiment with the realization of the virtual interface I/O, with the aims to transmit two audio stream on the platform. What I did was as follows: I have realised two virtual interface I/O where the virtual interface of type I contains the BlackHole 2Ch and microphone, while the second virtuale interface of type O contains the BlackHole 2Ch and loudspeaker. The objective is to transmit the audio of a YouTube video, in addition to the voice captured by the microphone, to the platform. However, it seems doesn't work well because Chrome forces that the virtual interface of type has only one audio stream. In that case, the audio stream is captured and transmitted. Perhaps it involves the development of audio stream processing in correlation with media streams?
