UPDATED: SO, my post previously was Oct 3rd, and just yesterday it repeated the issue so unplugging the tv fixed the tv again but has proven to be a temp fix. Because a little over a week past and it did it again.[br]
so now I’m contacting Vizio.
>>>>>old post below of what I tried <<<<<<<
Same exact problem! Since I bought the TV like 2wks ago. Intermittent sound from TVspkrs for hdmi connected devices.
-not on mute, settings for TV & PS4 & AppeTV correct for audio
-external sound works, remote works, video works
-changing input sometime worked
Issue persisted with the above mentioned
I’ve now just tried the unplug and pressing power for 5seconds
Tv is now doing audio output on all connected devices
Will check back to update as this issue previously would happen everyday
