Bug Description

Setting "Automatically switch all running streams when a new output becomes available" breaks all audio. Setting from the System Settings -> Multimedia -> Audio Volume -> Advanced. After next boot the audio is gone. Pulseaudio refuses to start. And while the pulseaudio doesn't start up, the setting that caused this is now grayed out and can't be taken of. Leaving you with crippled system. This happens in Kubuntu 17.10.

The reason this happens, I believe, is that the setting puts the pulseaudio switch on connect module somewhere. And at least with 17.10 this is already defined in the pulseaudio configuration by default. Pulseaudio somehow doesn't like that it is defined twice.

I solved this by temporarily disabling the module from /etc/pulseaudio/, rebooting, switching off the setting from the System Settings and the re-enabling it from the /etc/. That is hardly something easy to do...

This isn't working for me. I disabled this module:
### Should be after module-*-restore but before module-*-detect
# load-module module-switch-on-port-available
from the /etc/pulse/

but the setting is still grayed out, and I still have no sound. What other file/module can I modify to reverse having set this?

If I knew exactly which package this applied to, I'd be more than happy to file a bug. The problem is I have no idea, and all my searches turn up the same thing. Nothing specific. Just like this one, he "disabled the module", which module? He also disabled it in "/etc/pulseaudio/" I don't have a "/etc/pulseaudio" directory, it's just "/etc/pulse" I'm not sure which package is causing this, and I would just like to know how to fix it.
If you could direct me to the proper package, and/or bug already submitted I'll be glad to go there.
