I can not receive streaming audio on my PC ihave sound if I play movies it only don't work if I won't to listen to live audio

What are you using to listen to the stream? Most likely the software is not installed correctly or you are missing a codec. A codec is basically what encodes and decodes the audio and/or video signals. Different codecs are used for for different types of files. The codec used to view an AVI file is different from the one used to play a Real Audio or QuickTime file. Most third party players will install their own codecs so you don't have to worry about it.
