Here is a very short script that might come in handy if you wan't to quickly be able to disable/enable your microphone.
Since ALSA subsides under PULSE there is no way to add 'On/Off' functionality without using the ALSA toggle.
Usage:
chmod +x endimic.sh
./endimic.sh -o on It will set microphone state to on.
./endimic.sh It will toggle the microphone's state.
