Comment 13 for bug 1709163

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.
