how to fix choppy sound?

I'm experiencing choppy sound during a live video stream. Streaming over ethernet. The connection status is "excellent". Streaming 1080i through a black magic intensity shuttle thunderbolt on to a Mac Mini running Maverick OS. Was told by customer support to stream on Firefox. Tried to change streaming from LAN to DSL (was told to do that by customer support as well). Choppy sound still a problem. Any suggestions?
