![]() If you have a Sonos Beam or Sonos Arc, however, you’ll notice that you only have an HDMI ARC input (or eARC on the Sonos Arc). You can still have your AV receiver connected via ARC for any smart apps. You can use an HDMI switch to increase the number of inputs of your sound device. If you have a soundbar or an AV receiver that has one or more HDMI inputs, then plug in your Sky Q box, Blu-ray player or other device directly. The absolute best way to avoid these issues is to bypass HDMI ARC for external devices altogether. ![]() We’ll show you how to adjust settings to fix both. Lip-sync issues can present in one of two ways: audio comes before the picture, or audio comes after the picture. If, on the other hand, you run smart TV apps or plug devices directly into a soundbar then all should be good. In short, if you run HDMI ARC, you may see processing delays that throw audio and picture out of sync. However, not every device implements lip-sync properly, and the TV can cause further delays with its own processing. HDMI ARC does feature a lip-sync setting, which is supposed to carry information about how to adjust for the delay, and HDMI eARC has an improved version of this. Note that this only happens for devices plugged into the TV if you’re using smart apps, the TV seems better able to handle the processing. With HDMI ARC, everything passes through the TV, which can cause things to get out of sync. The reason for this is that an AV receiver can internally line up the audio and picture before sending the image to the TV. Lip-sync problems are when the sound and image become out of sync – and they tend to be more apparent with HDMI ARC connections, rather than with devices plugged directly into a soundbar, such as the Sonos Arc, or AV amplifier.

Look online and you’ll see forum post after forum post complaining about Sky Q and, in particular, Sonos soundbars (the Arc and Beam) suffering lip-sync issues. Our brains are hard-wired to line up mouth movements with what’s being said, so even minor issues can become distracting. Once you notice a lip-sync issue, it’s pretty much impossible to ignore it. Here, we show you how to fix lip-sync issues with Sky Q and Sonos specifically, although these instructions apply to any other device plugged into your TV. But the reality is that HDMI ARC and even the new HDMI eARC standard cause problems. Check the Cablesįaulty cables also cause desyncing, so check on the cables and use replacements if available as part of the testing process.HDMI ARC is brilliant, letting you connect a soundbar to your TV with a HDMI cable and routing everything through the TV. You’d be surprised just how many issues this simple step resolves, including audio lag. If this doesn’t work, go one step further and try restoring both gadgets to their factory settings. Restart both the television and the soundbar and see if that syncs them back up together. The same goes for soundbars and TVs falling out of sync. You know the old adage, when in doubt, just restart. The best option here is to shoot for a negative delay on the part of the TV. Check the settings of both your television and the soundbar, looking for “audio delay” or “lip sync.” Adjust as necessary and keep trying out your system to see if the problem has resolved itself. If your system suddenly starts exhibiting audio delay during use, you will need to resync your soundbar to the TV. This depends on your specific setup and the devices involved with your system if you are comparing Jabra 410 vs 510 systems or related queries. As a matter of fact, it is even more important than cable management if you are learning how to hide soundbar wires. Syncing is a must no matter the design of your living space, even if you are looking for the best boat speakers. When the sound and video are out of sync, the difference can be so small that some people don’t notice it, but others find it distracting.
