The problem existed even before I upgraded to 17.10. but now I can not go back to that version.
I think it started to happen when upgrading the kernel version. I thought that it would eventually be fixed but apparently I'm about the only one seeing this. What I do not understand is why it changes as the selected output is present all the time, and especially when I turn off a screen that has no audio associated with it. The monitor has no speakers. the only think I can think of is that the display subsystem is doing some reinit when I turn off the monitor and might remove the HDMI audio associated with the other monitor that still is on and then reinserting it. But why do pulse audio then switch over to that ?? is this some auto thing like if I put in headphones. the old GUI(unity) I could directly select sound config from the top icons. but now I have to first go to setting then sound so its even more work than before to get sound back. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1709163 Title: default output changes from intel builtin to hdmi when display is turned off. yes off not on Status in pulseaudio package in Ubuntu: New Bug description: So if I have sound output selected to be the intel sound on the mainboard and turn off one of my two displays the audio out is changed to HDMI. YES OFF it's not a typo. The Display I turn off is connected to displayport and do not even have HDMI. The audio is switched over to the still active display. If I then turn the display back it's still hdmi. If I then turn off the display that has HDMI out connected. the audio is still connected to that display. since its actually off I hear no sound but pulseaudio still connect to it. I have to manually open the GUI tool and change back to the correct output when the display is turned off or when the display is blanked. or suspend/resume.
