How can I completely disable audio drivers and services in my CentOS7
system?

This system is a server that will never run any audio applications.  The
problem is, I can't disable the audio device in my BIOS, so the system
finds it in the PCI device list and configures it on each boot.

Yes, I know I can blacklist specific device driver modules, but I've got
a minimum of 11 audio-related kernel modules loaded on a default C7
configuration, and untold dbus baggage to go with them

So.. what can I do to have CentOS7 completely ignore the audio hardware
it finds?

If I'm not mistaken, audio hardware is one source of entropy for the
kernel.

How can it contribute to entropy without a microphone attached?

Is it causing a problem?

Only to the extent that the resources used to support the audio subsystem could be allocated to services that are actually used.
