Onboard audio not being detected

Recently my audio stopped working. I just did a reboot and the speaker/mic didn't show up in pulseaudio. I thought it might be because of an update, so I rolled back my entire system from archive to a date when I knew that it was working. When that didn't work, I looked at the forum and found that others who have faced this issue in the past were able to fix it by setting this kernel parameter:

 snd_intel_dspcfg.dsp_driver=1 

However, this did not work for me. I am including the lines from dmesg where the error occurs, and the output of lspci for my audio device.

00:1f.3 Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10)
	Subsystem: Lenovo Device 3812
	Kernel driver in use: snd_hda_intel
	Kernel modules: snd_hda_intel, snd_soc_skl, snd_sof_pci

Also, it seems that other people have had issues where sof-firmware was not installed, so I want to mention that I do have that. In addition, I want to mention that I have been using arch on this laptop for over 2 years now, this same install, and never had to change anything manually to get audio working. I'm not sure how this issue just randomly cropped up. Any help would be greatly appreciated.
