Adding "No Device" option back like pre-7.x so that there are no accidental or unintentinal breach of voice input at any time. There used to be "No Device" option on Voice Audio Input settings before but no more... now we have to select at least one audio input device. Removing all of them is quite impossible and there might be accidental breaches through various devices that can have voice input (webcams/headsets/even nvidia broadcast) etc. Especially when you want to hear other Voice chats but not broadcast yourself.
