Hugh Chao: I followed your instructions exactly and I restarted my HP PC, but GNOME Settings shows dummy output for my audio card for audio output and nothing for audio input. Here is some technical information:
alsa-ucm-conf is already the newest version (1.2.2-1ubuntu0.1). linux-generic is already the newest version (5.4.0.7634.38~1591219791~20.04~6b1c5de). 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. root@late2019hpomen15t-pop-os:/boot# uname -r 5.4.0-7634-generic root@late2019hpomen15t-pop-os:/boot# inxi -Ax Audio: Device-1: Intel Cannon Lake PCH cAVS vendor: Hewlett-Packard driver: sof-audio-pci bus ID: 00:1f.3 Device-2: NVIDIA TU104 HD Audio vendor: Hewlett-Packard driver: snd_hda_intel v: kernel bus ID: 01:00.1 Sound Server: ALSA v: k5.4.0-7634-generic root@late2019hpomen15t-pop-os:/boot# I did decide to remove the few lines of code from /etc/pulse/default.pa and I removed the line of code from /etc/modprobe.d/alsa-base.conf before I restarted my HP PC and it resulted in dummy output and no detected microphone. I am going to re-add those lines of code and restart my HP PC again.

[Fix] Intel upstream 2 patches in the kernel to fix it. [Test Case] Boot the kernel on the machines without Intel HDMI audio, everything works well including the audio. [Regression Risk] Low, these 2 patches are already in the mainline kernel. On Ubuntu 20.04, by default, sof-audio-pci is used. I only have "Dummy output" in pavucontrol. To fix this, I modified /etc/modprobe.d/alsa- base.conf and added "options snd-intel-dspcfg dsp_driver=1" so that now "snd-hda-intel" is loaded instead of sof-audio-pci. While the speakers are working fine, I do not have the internal microphone working (suspect a digital array).
