Audio and video usually fall out of sync because something in the playback chain delays sound or picture: Bluetooth processing, TV picture processing, a connected device, or the broadcast or streaming source itself. Compare a few channels, apps, and inputs first. If the mismatch affects everything, check the connection and the equipment’s audio/video sync setting; if it appears in only one source, start with that broadcaster or service.
First, work out where the sync problem starts
Note whether speech is visible before you hear it, or the sound arrives before the person’s mouth moves. Then try the same kind of content from another channel, app, title, or connected device. This helps distinguish a source-specific fault from a delay affecting the TV or audio equipment.
- Only one channel is affected: The broadcast signal may be the cause. LG says a sync problem limited to one channel is highly likely to be related to that channel’s signal. LG’s troubleshooting guidance recommends checking whether other channels behave normally.
- Only one app, service, or title is affected: Suspect its stream or app before changing the entire system. Try a different title or service; if the problem remains isolated, report it to the service. Roku similarly recommends narrowing down whether the issue involves the Streambar, TV, or connected device, and contacting a streaming channel when the fault is limited to that channel. Roku’s Streambar guidance explains this source-by-source approach.
- Several sources are affected: Check the connection path, audio device, and TV settings. A shared part of the setup is more likely than a single broadcast or stream.
Common causes of audio and video delay
Bluetooth audio processing
Bluetooth can introduce a delay because devices buffer or process audio before playing it. Depending on the connected device, the mismatch may change during use. Sony notes that Bluetooth devices can process sound differently, making it play before or after the picture; JBL also describes buffering at the Bluetooth receiver and possible delay from a TV’s Bluetooth transmitter. These explanations apply to the products and situations covered in their support pages, not necessarily every Bluetooth setup. See Sony’s BRAVIA lip-sync guidance and JBL’s guidance for Everest 300 and Everest 700.
TV picture processing and connected equipment
Picture processing can affect when the image appears relative to sound. A connected source, audio device, or the material being played can also contribute. Sony lists processing, connections, and disc material among possible factors, while JBL suggests testing with image processing disengaged where appropriate. The exact processing controls and their effects depend on the model.

A fault in the broadcast or stream
If the mismatch follows just one channel or service while other sources stay in sync, the source is a stronger suspect than the TV. A stream can also have a temporary playback problem. Refreshing the app or stream and comparing another service can help separate a source issue from a device or connection issue.
Timing limitations in the playback chain
Audio and video pass through multiple devices and processing stages, and they do not always arrive together. Sony cautions that some synchronization delays can reflect general technology limitations rather than a defective TV. That guidance concerns specified BRAVIA products and is not a diagnosis of every television.

How to troubleshoot the mismatch
- Describe the direction. Record whether sound leads the picture or trails it. This is useful when testing settings and when explaining the problem to support.
- Compare sources. Try another channel, app, title, or input. If one source alone is affected, refresh that stream or app and contact its provider if the problem persists. If several unrelated sources are affected, continue with the shared equipment.
- Check the audio route. Identify whether sound is coming through TV speakers, Bluetooth, HDMI, or optical audio. Reconnect the affected device. If Bluetooth is involved, test the TV speakers or a compatible wired HDMI or optical connection. Sony recommends these alternatives in some Bluetooth-delay cases. A wired connection is a diagnostic option, not a guaranteed fix for a bad broadcast or a processing mismatch; both devices must support the connection.
- Look for a sync setting. Search the TV, soundbar, or receiver settings for labels such as A/V Sync, Audio delay, Lip-sync, or TV Speaker Delay. The feature may be on the TV or audio device, and its name and menu path vary by model. LG describes adjusting TV speaker delay on supported configurations; Roku notes that settings may use names such as Audio delay or Lip-sync.
- Adjust gradually while replaying the same scene. Make a small change, watch and listen again, then continue only if the mismatch improves. Do not assume that increasing or decreasing a number will correct every setup: manufacturers implement controls differently, and the right adjustment depends on which arrives first.
- Test processing and refresh the source. If the manual provides a picture-processing control, try turning the relevant processing off temporarily. Refresh the affected stream or app, compare another service, and check for relevant software updates for the TV or connected device. Retest the same scene after each change so you can tell what helped.
- Escalate with useful details. If the issue remains, note the TV and audio-device models, affected channel or app, connection type, whether other sources work, and the sync setting you tried. Contact the broadcaster or streaming service for an isolated source problem; contact the equipment manufacturer when multiple sources show the same fault.
What to know before changing settings or connections
- Use the manual for your exact model. Sync controls and menu paths are not universal. Sony’s guidance is model- and operating-system-dependent; LG and Roku describe settings for supported configurations.
- Do not buy equipment before isolating the cause. A compatible wired HDMI or optical route may help diagnose Bluetooth delay, but it will not correct a faulty broadcast or every processing mismatch. The cited guidance does not establish that replacing a soundbar, receiver, or TV is generally necessary.
- There is no universal delay figure or target in the cited guidance. Sony, JBL, LG, and Roku do not establish a representative typical delay or a general millisecond setting for home lip-sync problems. Use the same scene and your own equipment’s controls to judge whether a change improves synchronization.
