Hello, i have a sonos play 1 and no ability to have internet at home, I can go to the library to use internet. There is no audio jack on the speaker jjust a power cord and what looks like an ethernet port. Is there no way to listen to music or plug it into my tv to use it. It seem rediculous that i cant use it without internet.. Is there a cord that would allow me to connect the ethernet cord to an audio line so i can watch movies or listen to music?
