What type of music files and streaming protocols can I listen to by Internet radio? You can listen to MP3 and WMA music files by the Hyper Text Transfer Protocol (HTTP). Why can't I hear Internet radio through my receiver? Please make sure of the following: (1) Are you using a broadband Internet service, such as ADSL, CATV or FTTH?; (2) Make sure devices on your LAN are receiving power and are connected properly.
