Bug description:
  This is for alsa-ucm-conf:

  The patches are already in the mainline alsa-ucm-conf, so only
  sent the SRU for focal

  [Impact]
  On the machines without Intel HDMI, the sof driver will fail to initialize.

  [Fix]
  After fixing the kernel, we also need to change the ucm2 to make it
  support the machine without Intel hdmi audio.

  [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 alsa-ucm-conf. And we
  already tested them on 4 HP machines.

  
  This is for linux kernel:

  The patch is already in the oem-5.6 kernel and unstable kernel, so only
  sent the SRU for focal

  [Impact]
  On the machines without Intel HDMI, the sof driver will fail to initialize.

  [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).
