Juce Demo Host Issue

Hi, I was using host application for testing my VST plugin. Suddenly audio input filter’s pin disappears. I am newbie and didn’t know what exactly happened to this.
Due to this i am unable to test plugin.

You probably need to select another input device. Select “Change the audio device settings” from the Options menu:

I’ve also just pushed a commit which allows you to double click on the “Audio Input/Output” node to bring up the device settings. Hopefully this will be more intuitive.
