It seems that whenever you connect a new device it is set as the currently active one. I suspect the device selected as active after the restart is simply the last one to load.
I just tried this with 3 devices: 1. at first have device A and B connected to the computer and have B selected as active 2. connect new device C 3. I can see C becoming automatically the active device 4. disconnect device C from computer 5. A automatically becomes the active device all of the above was monitored by having the "Sound" panel of gnome- control-center opened and watching the "Output" > "Output Device" Combo- box changing. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1924852 Title: Selected output device in Sound settings is not persisted across restarts Status in gnome-control-center package in Ubuntu: New Bug description: # Introduction My computer has multiple audio devices, so I had to select the correct one in the "Sound" section of "Settings".
