Hi everyone,
When it comes to the lip sync, the Beam should be playing your audio as soon as it gets it, with a very minimal delay about 30ms (which is around 1.8 video frames at 60fps, considered to be imperceivable). The timing of the audio is based on when the TV sends it. We've found that some TVs have trouble sending Dolby Digital audio over HDMI-ARC while at the same time processing high-quality video.
In some cases, the manufacturer has addressed it already, and an update for the TV could solve the issue. I'd suggest making sure your TV is updated, and it would be good to contact the manufacturer to ask if they are investigating an audio delay issue with connected home theater devices playing audio.
Some TVs you can clear up any delay simply adjusting the settings can help improve things.
I'd suggest starting with checking the settings on the source device of your video that's behind. If it's a cable box or source where you can edit the audio settings, see if you can set it specifically to Dolby Digital 5.1. Also if the TV has any processing or audio effects that are adding extra processing like an ULTRA mode or Clear Audio+, try turning those off.
If you're not concerned about getting Dolby Digital audio, you can set the source device to PCM or Stereo and the delay will likely go away, as that format is easier to transmit.
Also, we're happy to take a look at your setup with you and see if we can help. We'd also like to get more details on what setups are seeing this sort of issue so we can investigate with the manufacturers further. I'd invite you to
give us a call on our support line so we can work on this together.
