I recently bought a Nintendo GameCube.
I connected it to my desktop monitor through a AV to HDMI converter, as the monitor does not have AV. However, the audio doesn't work, because my monitor has no built-in speakers.
I'd like to either play the sound through my Macbook Pro's speakers or through a pair of headphones. I'm assuming the former would be easier, as most headphones don't have volume control.
I tried purchasing a simple adapter online. This didn't work, and I'm assuming it's because the audio needs to be converted from analog to digital.
How do I route the sound from my GameCube into my MacBook speakers, or earphones?

You can do it with either with a headphone amplifier that accepts stereo analogue input, or a laptop with an analogue line in or microphone input (though the later is less than ideal.)
In the first case you'll need to either connect the GameCube's red and white RCA connectors on the end of its AV cable to the headphone amplifier directly or you'll need to use the adapter you've already bought. In the second case you'll need to use your adapter to connect into the input on your laptop. You'd then need to find the option in OS X that lets you monitor the line in or microphone input through your laptop's speaker. I don't have a Mac so I know where that would be.
