I just started using a spare Apple TV to extend my desktop to a 21" LCD. It's mostly for background tasks. I have a standing desk, and a couch in my office. Half the time I'm at the couch working with my laptop, and I'd like to be able to put videos up on the 21" LCD at my standing desk that I'm reviewing. This is working great now, but the cheap LCD has terrible speakers and it doesn't have an audio out. SO, what do I need to use the Optical out from the Apple TV with standard desktop speakers? Is this going to work: http://www.amazon.com/Recoton-Fiber-Optic-Toslink-Adapter/dp/B0002MQGRM Or will I need an actually converter: http://www.amazon.com/Digital-Audio-To-Analog-Converter/dp/B0013LWK3A And if it's a converter that's needed, what's the cheapest that will work? This isn't mission critical work, but it would be great to be able hear decent audio through the Apple TV. If the Optical audio port is in use, does it choose to send the audio over that even when HDMI audio is available? Thanks.
