Origin is anything the user would choose to play on a "normal" system. Pure sound from CD, mp3, ogg, wma played with xmmls, totem movie player etc. Any application used to play sound on a Linux box. The PCM stream would be compressed and transmitted over TCP/IP to the smartphone which would play it on its output. Thanks, Olof
