I ran alsa-info before/after running "sudo alsa force-reload" to see if
there were any obvious differences in the output. While there are a few
differences, nothing really stands out as causing this issue.

Title:
  Built-in audio device not available until alsa is reloaded

Status in alsa-driver package in Ubuntu:
  New

Bug description:
  I had Ubuntu 18.04 installed, running XFCE (Xubuntu session), and
  audio worked fine, using either the built-in speakers/mic on the
  laptop or via a USB headset when that was plugged in.

  However, after upgrading to 20.04, the built-in audio device is no
  longer available until I run "sudo alsa force-reload". Wthhout that
  WAR, all I see is a dummy audio device. Luckily the USB headset works
  fine, if plugged in.
