Nice to hear from you Tom.

My volume control popup showed up today ;)

Recent hardware is Gigabyte board with onboard audio:
   "Audio device: Advanced Micro Devices [AMD] nee ATI RS880 HDMI Audio 
[Radeon HD 4200 Series]"

chipset is Realtek ALC892.

Do you know where I could find a flowchart or some graphical 
representation of how things come in and things go out and they shake it 
all about?

alsa wiki about this was most recently updated three years ago.  pulse 
vs jack was also 3 years ago.

I know I can't be the only person wanting to understand fedora/linux sound.
