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? Thanks.

Is it causing a problem?
