Why can’t I hear any audio/sound?

Check that the volume in the XFINITY Stream web player is not muted and that your speaker volume is at an adequate level.


  • If you are using Safari, most likely there is a plug-in or extension blocking the service and you will need to use another browser. See below also.
  • If you are trying to connect your laptop to a TV via HDMI, we do not support that due to licensing and digital rights agreements. See below also.
    • We highly recommend purchasing a Roku device to use our XFINITY Stream channel to watch Live TV, On Demand, DVR recordings and more right on your TV set. For more information on Roku Beta, click here.
