A simple script that creates a virtual microphone which adds system sounds to your default mic output. This can be quite handy for voice chats, if you want to share some audio samples or streams with your buddies without muting yourself.
This is a Linux script so it probably won't work on other operting systems. It also assumes that your system uses pulseaudio by default. Most linux distros and applications do nowdays.
Run the script as a regular user and follow the instructions
$ chmod +x micmixer.sh # if necessary
$ ./micmixer.shAfter you hit ^C it will try to undo all the changes. Note that all the
changes made by this script are non-root and run-time (i.e. it doesn't
modify any config files). Therefore, in case anything goes wrong things
should get back to normal after a reboot or
$ killall pulseaudio
