Hey, we recently got a new TV, its a 4K Seiki and we use a virgin media TiVo on cable. We've found that on all non HD channels, the audio lags a fraction of a second behind the video. On HD channels the AV is perfect. Would be awesome if anyone has any possible solutions to this problem. Thanks
Welcome ASovietDuck and thanks for popping along and posting on the community with us.
I'm sorry to hear about the trouble you've had with audio lag.
I've managed to locate your connection and have run a few checks and all the levels into the TiVo appear healthy. I've had a quick look around Google and there does appear to be a few search results on this particular subject specifically with 4K TV's. As a suggestion there may be some options within the audio settings of the TV to correct this.
I've had the same problem for years, ever since switching from Sky to Tivo. Never found a solution, and just gave up. It only happens on HD channels, as much more picture 'data' to process, which makes it lag behind sound. Upgraded software on TV etc, but nothing has cured it. Certain HD channels are totally unwatchable as the sound and picture are so far out, it's too distracting to try and watch. It only happens on HD, Sky boxes had an audio delay option which could be used to fix the issue when connecting audio equipment. No such options on Virgin as far as I know.
