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.

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.
