module-switch-on-connect switches to virtual devices

Bug Description

The module-switch-on-connect module that has been enabled by default in Artful is causing virtual devices added by PulseEffects ( to be activated and set to the default/failsafe device. This also changes which device the system volume control changes. It should only automatically switch when a physical audio device is plugged in. If there is no way to detect this automatically, then I would say this should not be the default configuration, or it should be added as an optional preference. In the meantime, I have worked around the issue by copying /etc/pulse/ into ~/.config/pulse and commenting out loading the module.

I don't think that Ubuntu developers can do anything with it, they will not disable propper handling of USB dongles to allow PulseEffects work properly and solve

This sounds like a valid bug still, but low priority if PulseEffects is not part of standard Ubuntu. So most people will never notice. We're working on the assumption that many more people want USB and Bluetooth devices to work well, than PulseEffects.

But still, this sounds like a valid bug. Please log your request for switch-on-connect to ignore virtual devices here:
