Status:

Before I install the BIAB & RB 2001 upgrade on top of my 2009 version...
(which was just "installed" from my never used 2009 BIAB supplied hard disk... using the supplied installer exe file)

I decided to see what sound card was in this (old, but beefy) custom Intel I7 Win10 PC.

Device Manager tells me I have these installed in c:\windows\system32\drivers

(qty 4) NVIDIA HIGH Definition Audio
(qty 1) NVIDIA Virtual Audio Device (Wave Extensible) (WDM)
(qty 1) Realtek High Definition Audio

Questions:

1 - I guess these are all drivers... but why so many? What do they all do?
(as far as I know there is only one sound card plugged into the mother board)

2 - Does any of this information tell me what sound card (hardware) I have in the PC?
Is it a Realtek card with a bunch of NVIDIA drivers or the reverse or what?

Reason for Asking:
I'm guessing this info will be helpful during the installation and later steps to get my M-Audio Axiom 49 keyboard controller setup to record into RB)

I'll have more questions later as I navigate my way through this so...

Thanks for any help along the way.
