What is this cable (see link for pic)? One end is a standard 1/8inch speaker jack, and the other end looks like a wireless transmitter/receiver. Also, the other side of the 'wireless' end has a 3M adhesive sticker on it.
Someone on the city-data.com forum suggested that it is an infrared transmitter cable, and I think that may be right. I remember buying a TV tuner card 10 years ago with an infrared remote. My guess is it goes to that. Thanks for the thoughts!
