I have a similar issue where the input and output are reset on each new session. This doesn't happen on other non-Ubuntu distros with GNOME 3.36.1. Let me know if there are any relevant details that would be helpful.

Every reboot this settings is lost and the system defaults back to the USB output. I have several other distros to test - Ubuntu and its flavors are the only ones that have this problem. Something changed in 19.04 or 19.10 that broke this, and it continues to be an issue in 20.04.
