If anyone has a tutorial that they would recommend, I would appreciate a directive to it.
I had looked at pavcontrol and "think" i have a handle of its visual layout mimicing wiring to accomplish proper audio functions (microphones and speakers) that today's environment layouts present. It appears to be well-thoughtout approach to make these behavior efforts a visual for easy understanding.
In my initial attempt at understanding, it seems to show how a system's subsystem/application is 'WIRED" to a physical device. Is this a truth?
Help requested in correcting this view.
