Analog audio via UTP twisted pair

Hi all! Every time I want to listen music from my collection in another room (ex. kitchen), I have to take my tablet, connect it to audio system and setup streaming over WiFi. It's boring.
But what about direct audio from sound card to another room without network transcoding? I know there are devices starting from low costs to high-cost multiroom systems. Not my choice. It is interesting for me to make some kind of "multiroom audio" by myself =)
