So, for the past few days I've been rampaging through the internet searching for a guide on how to make an LED light up when sound is being played on the computer. What I want is for the arduino to pick up sound I get when someone messages me on skype, for example. I thought that if I could get it to react when my computer makes a sound, I could direct the sound that skype makes and make that as an input for the Arduino. My question is, how do I make the arduino recieve information from other sources on the computer.
FYI - I'm kind of new to coding and the arduino so keep that in mind.
Why would you be more likely to be looking at a LED when it happens to light up? Wouldn't you be better off to turn your computer speaker's volume up high or add an amplifier so that the sound can be heard throughout the house?

It occurred to me that you (or whoever this is for) might not be able to hear the computer sound in which case an amplifier isn't going to help.
It should be possible to connect the audio output of the computer to a circuit which rectifies the audio and then generates a HIGH output when the audio exceeds a threshold. The Arduino can then turn on whatever device is appropriate, whether it is an LED or some other indicator.

I can hear the computers sound. The reason for me wanting to have an LED light up is because my music is often cranked up so I don't hear when I get a new message. So I wanted to find out if my computer could send information directly to my Arduino, through the usb cable, not that the Arduino picks up a sound through the speakers. May that solution be by cable or bluetooth component or a SHIELD, don't matter, I just need confirmation that it can work, or even better HOW you can do it.
With this I might just go off-topic, nevertheless, I want to find a way for my computer to send information to the arduino when someone sends me a message, for example if someone send me a message on skype, my computer would send that information to the Arduino and the arduino would process it to for example light an RGB LED blue, and if I get a steam message the Arduino would light red.
IF my computer could automatically send information to the Arduino
