![]() It also doesn’t work if you use your TV’s smart apps to watch Netflix, or if you watch local channels on an antenna plugged into your TV-in those circumstances, there’s no external box to plug into the soundbar, so you’re forced to route audio to the soundbar over delay-inducing HDMI ARC or optical. In fact, most affordable soundbars only have one HDMI In port, which means if you have a Roku, a Blu-ray player, and a game console, you won’t be able to plug them all into the soundbar at the same time (unless you use an HDMI switcher, which just introduces more wires and complexity). (This may introduce a video delay instead, if your TV is doing its own processing, like motion smoothing, but you can use the lip-sync feature on your soundbar to delay the audio to match.)ĭespite being the ideal audio delay fix, I mention this last because it comes with one big downside: most soundbars don’t have many inputs. But if you plug your Roku into the soundbar, then pass video through the soundbar to the TV via HDMI cable, any delay caused by audio processing will disappear-because your soundbar will wait to send the video to the TV until all its work is done unpacking the audio. ![]() If your Roku is connected to your TV, which then sends audio to your soundbar over HDMI ARC or optical, you’ll have to use the above (often imperfect) solutions to mitigate the delay. The best solution, in my opinion, is to re-configure how your soundbar and TV are connected. Plug your source into the soundbar instead of the TV Manufacturers try to fix this audio delay problem on their own, but there’s only so much they can do. ![]() Couple that with any other processing you’re doing-like motion smoothing on your TV, or “virtual surround”-type features on the soundbar-and you’re basically guaranteed out-of-sync dialogue. On the supplied remote of your soundbar or home theater system, press the MUSIC button to set sound mode to MUSIC. If the TV doesn’t know exactly how long your soundbar will take, it may send the video before the soundbar has finished, leading to a disastrous mismatch of the mouths on screen. But when you introduce another product-like a soundbar-your TV might decode the video while your soundbar decodes the audio. If you’re playing that audio on your TV’s speakers, your TV is doing all the unpacking, so it can hold off on sending both the video and audio until the process has finished. We’re talking milliseconds, usually, but time nonetheless-and higher bitrate formats (like multi-channel Dolby Atmos) might take longer than a low-bitrate stereo track, leading to a more noticeable delay. When that signal is sent to your TV or soundbar, the device has to decode the audio in order to play it over your speakers, and that process takes time. You will need to have the TV on while you make the adjustments so you can sync the audio with the show. The +/- symbol on the button indicates speeding up or slowing down the audio to match the show. In general, though, the audio is passed ‘as is’, on the grounds that the external device has its own settings you can use for this, and also, you don’t want the possibility of two lots of the same enhancement being over-applied.Specifically, when you watch a Blu-ray or stream a movie on Netflix, that audio is encoded in a certain format-like DTS or Dolby Digital. The first is to try the button on your soundbar marked audio sync. To do so, power off your TV and sound system. If you can’t get there, or you can but it is grayed out, this tells you the setting is for internal speaker operation only. The first thing you can try is to power reset your TV and sound system. Regarding any setting, such as Clear Audio+, where you are not sure if it is applied before or after the take-off for HDMI audio, get the TV working with the external audio device, and then try to go to the setting in question. BraviaSync is Sony’s name for their particular flavour of CEC, and its various ways of chaining husbands to 24/7 tech support duty.Ī/V Sync is for when the audio on an external device leads or lags the video on the TV, and you need to correct Read this, and then come back with any further questions:.
