Public bug reported:
After upgrading to an AMD laptop (Thinkpad T14) and Ubuntu 21.04, when I
boot the laptop my audio device has changed to HDMI, instead of
remembering my headphones from last session.
Screen remains plugged in, but takes a few seconds to wake up while
booting.
Commenting out
load-module module-switch-on-port-available
in /etc/pulse/default.pa fixes the issue.
