Please can you provide more information to what exactly you're trying to do.
I assume that you're trying to play a live audio only stream from 2 separate PC's both in sync with each other?
If that's the case this can be problematic using HTTP clients, I recommend the playback clients are both RTMP based players as the default chunk sizes are 10 seconds and so the time between any clients playing a live stream can be 10 seconds apart. Reducing the duration of the chunks for that HTTP client will make it more accurate, however if you're wanting them to play in sync I'd use a RTMP player.
Without more information I'm just guessing as to what it is you're trying to achieve.
Please be as detailed as possible when describing the workflow you're wanting.
