I have just installed the vizio co star on my network. When I try to use a live feed the sound cuts of after a couple seconds. I also try to use a google tv app called tune n view. I do not hear any sound at all. My current physical configuration of this co star box is I have the co star at a remote location and it auto connects to hdhomerun through my network from time warner, so I am not physically connected to the cable box through the HDMI in port on the co star. I only utilize the HDMI out directly to the monitor. Could anyone assist me on troubleshooting the issue I am having regarding the sound issues.
