Since Plex transcodes audio on the fly, it does have a + and - adjustment for audio. I found that pushing it ahead somewhere around 175 ms puts it perfectly in sync...
The Vizio has some audio output settings. I am not sure what effect that might have. I presume you have yours set on "Dolby Digital" which is where it would need to be to get multi-channel sound. You could try playing around with that setting, though, to see what happens.
If your receiver has HDMI inputs, your best option would probably be to run everything through your receiver first, and then just have one HDMI going to the TV from your receiver. Then, there should be no audio delay.
I suppose yet another option, if your receiver does not do HDMI switching, would be to separately hook up the audio from your devices to your receiver. For example, most cable boxes have a separate digital audio output that you could hook up to your receiver. Even though the HDMI cable would still go directly to the TV, you would effectively only be using it for video. In fact, if you hooked it up that way, on your receiver, you could swap back-and-forth between the input hooked up to the audio coming directly from your cable box and the input hooked up to the audio routed through your TV. That way, you could really hear if the problem is what you think it is. Of course, for any devices that only have HDMI for audio (i.e., no separate digital audio output), you cannot take this approach and have to route them through the TV.
