Q: Is there any way to get audio from a TV or cable box into AirPlay? I want to stream audio from Live TV through Airplay to my remote speakers.

A: Other than Apple devices such as the iPhone and Apple TV, there are no hardware devices currently available that can transmit audio to an AirPlay device.
The Apple TV and iOS devices that support AirPlay are designed to transmit content that is on the device and do not provide any way for connecting an external audio source to be passed through to AirPlay speakers.
If you’re willing to use a computer to do this, however, you may want to check out Rogue Amoeba’s AirFoil, a third-party app that allows you to stream any audio from your computer to an AirPlay device.
In this case you could connect the audio output from your TV or cable box into the line-in on a Mac or PC and then use AirFoil to stream it to a set of AirPlay speakers. Unless you’re already using a Media Center PC or Mac Mini as part of your home entertainment system, however, this option is probably more complex than simply running physical wires to the speakers.
