Having reinstalled and updated/upgraded to kernel `5.4.0-42-generic #46-Ubuntu SMP Fri Jul 10 00:24:02 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux` I can report the following info: --used "third party drivers" and ticked the box for secure boot, entered a password, but never saw the BIOS/UEFI prompt to enter the MOK password --turned *off* auto-login after installing; this may have been the source of the above-described issue, the problem environment had auto-login *on* --installed and configured a variety of Gnome and other apps (Chrome, docker, pipenv, vim, and so on), then ran apt update;upgrade again --have rebooted several time and not seen the issue, although the "normal" issue of defaulting to internal audio after reboot remains, if this solution https://askubuntu.com/questions/1038490/how-do-you-set-a-default-audio-output-device-in-ubuntu-18-04/1207638#1207638 fixed the issue in 18.04 wondering why it was left out of 20.04 GUI? --very strange behavior noted previously: worked with one HDMI Monitor (ASUS, I believe), powered down the laptop (HP Evo x360), took it to Samsung 55" TV, no HDMI audio detected or seen with lspci. Powered down the laptop, returned to the HDMI monitor, and *both* audio and VGA worked great!
I will provide any further testing/reports requested, I'd like to assist with perfecting this product; 20.04 rocks! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890285 Title: HDMI sound output cannot be selected anymore To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1890285/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
