Debian Testing installation notes
Main installation went smoothly, I installed gnome 3 and xfce, at boot it defaults to gnome. No sudo The installation process prompts for a root and user password and without thinking much, I set both. This resulted in my default user not being allowed to run commands with sudo. Add the default user to the sudoers group: # log as root, as the user is not allowed to use sudo yet $ su # add user to the sudo group $ /sbin/usermod -a -G sudo <username> It is necessary to log out for changes to take effect. No sound My Asus Xonar is supported on Linux (as of early 2019), however the installation default sets the card to stereo and probably uses a different output plug.
