Problem solved: Have sound coming thru tv via hdmi no analog audio needed.
Steps taken
1. Went to device manager then scrolled to my sound video and game controllers tab , clicked realtek audio which is my audio for my comp uninstalled then restarted comp and auto installed my realtek high definition audio and went to
sound clicked playback tabs and presto hdmi audio has now popped up as and option and everything is as it should be.
Side note vizio customer service are idiots and where not helpful at all and told me that hdmi would only carry video to there tvs and not audio and that i would need to hook up analog audio right next to hdmi port 3 which i was told is the recommended port to hook up pc connection which i have found nothing of this sort to support that in the owners manual unless you need to hook up analog with your video source which did not work for me anyway.
Once again thinking that you can resolve any issues with customer service is a pipe dream, with them reciting the standard 1-10 steps that of course you have tried and having ten times the amount of knowledge within ten minutes of owning the device.
