I'm aware that this topic has been well documented. Unfortunately I'm still having trouble so hopefully someone can give me a hand.
I'm trying to completely blacklist the on-board sound card in my PC as I have a dedicated sound card for digital audio that works great. The problem I'm encountering is that the system detects two audio devices and sometimes loads them in a different order. This causes problems for most of the applications I use.
So far I have blacklisted the pcspkr module in /etc/rc.conf.
MOD_AUTOLOAD="yes"
#MOD_BLACKLIST=() #deprecated
MODULES=(fuse !pcspkr !floppy)Before I blacklisted pcspkr, my optical S/PDIF would not work at all. It works great now but ALSA still detects two audio devices. For example, in VLC audio settings under "device" my options are (default, HDANVidia:ALC1200 Analog (hw:0,0), HDANVidia...(hw:0,1), ...(hw:0,2), C-Media CMI8762: C-Media PCI DAC-ADC (hw:1,0), ...(hw:1,2). Sometimes C-Media is hw:0 and sometimes it is hw:1. I would like to remove Nvidia HD audio completely.
I will include some information that I think is pertinent although I'm not sure how to use it.

Blacklist at least snd_hda_intel and possibly snd_hda_codec_nvhdmi too.

Can I test which modules I want to blacklist by using modprobe -r, or is that a permanent change?
EDIT:
I added !snd_hda_intel to MODULES in /etc/rc.conf. This fixed the problem.
Thanks.
