DP probably isn't the best place to ask this, but here goes anyway... I've got CAT5 running through my house, and want to pipe analog audio from one room to another. Can I simply wire up an RJ45 to take the audio signal into the other room? There's nothing else running on the CAT5 and it doesn't go through any switches or anything. It just runs from A to B. I figure it would be a nice cheap way to get audio into another room without having to screw around with WiFi, but I don't want to spend any time soldering up an adaptor if it's already been tried and failed.
I've already got the PS3/mediaserver/WiFi thing going on which is fine for watching movies over WiFi, but I'd also like to run iTunes/Winamp on a wire for when my PS3 isn't on (or is being used for gaming).
OK. I'm answering my own question for any other desperados discovering this thread via Googs. YES it's possible to run unbalanced line level audio across CAT5. You need to untwist the standard CAT5 pairs and re-pair them (see below), then simply solder the 4 new pairs to 2 RCAs (or whatever you're going to use): Blue/Orange > Left RCA tip Blue+White/Orange+White > Left RCA shield Green/Brown > Right RCA tip Green+White/Brown+White > Right RCA shield I'm not sure about how it would go on long runs, but I've got it working across apx 20 meters - from a Delta 66 audio card, into the wall and through the house, then into a NAD 7125. No noise, no hum. It works.
