I am trying to attach USB device used for tele calling which have pnp sound controller for mic and speaker. Now i have two speaker and two mic for input output as shown in image below.
![speaker]()
Now my motive is to transfer audio stream from system mic to external sound card mic and from external sound card speaker to system speaker.
What can be the possible solution that can be attained using c#.
I don't have knowledge about this, so don't know how to start.
