HDA Intel not being loaded as a valid audio device for ALSA

Hey,

So I've spent several hours trying to research my problem at this point and I've had trouble finding someone who has a similar issue.

I should have two audio devices available, Nvidia's HDMI output, and my integrated Intel input/output; however only the Nvidia device is present. The Intel device is not present in amixer, and was not present in pavucontrol when I had Pulseaudio installed (It is uninstalled presently while I try to narrow down my point of failure).

Below is some relevant lspci output which shows that the device exists and is being found by the operating system.

00:1f.3 Audio device: Intel Corporation Sunrise Point-H HD Audio (rev 31)
        Subsystem: Gigabyte Technology Co., Ltd Device a0b2
        Flags: bus master, fast devsel, latency 32, IRQ 132
        Memory at df320000 (64-bit, non-prefetchable) [size=16K]
        Memory at df300000 (64-bit, non-prefetchable) [size=64K]
        Capabilities: [50] Power Management version 3
        Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
        Kernel driver in use: snd_hda_intel

01:00.1 Audio device: NVIDIA Corporation GP106 High Definition Audio Controller (rev a1)
        Subsystem: eVga.com. Corp. Device 6161
        Flags: bus master, fast devsel, latency 0, IRQ 17
        Memory at df080000 (32-bit, non-prefetchable) [size=16K]
        Capabilities: [60] Power Management version 3
        Capabilities: [68] MSI: Enable- Count=1/1 Maskable- 64bit+
        Capabilities: [78] Express Endpoint, MSI 00
        Capabilities: [100] Advanced Error Reporting

The only reference to intel sound with pacmd being run was

alsa.driver_name = "snd_hda_intel"

. Despite this, /dev/snd/ seems to only have the Nvidia device present.

This started after attempting to pass through my sound card to a Windows VM I had, however I have since completely reinstalled Arch Linux attempting to fix this.

The most common solution here and elsewhere seems to be a modprobe.d conf script, which I've attempted to no avail. Does anyone have any potential solutions?

Re: HDA Intel not being loaded as a valid audio device for ALSA

aplay -L
cat /etc/asound.conf
systool -vm snd_hda_intel
dmesg

notice that the nvidia device will very likely use snd_hda_intel as well
