Why is my streaming video and audio out of sync Android?
Audio and video falling out of sync is a common issue that many Android users face when streaming videos or using video calling apps. This article provides an overview of the various causes of audio/video sync problems on Android devices and offers potential solutions to help users troubleshoot and resolve the issue.
We will examine sync issues related to software like media players and apps, hardware components like speakers and microphones, network connectivity, codecs, and device settings. Troubleshooting steps like contacting the app developer, factory resetting the device, and more radical solutions will also be explored. The goal is to provide Android users with a comprehensive guide to diagnosing the root cause of their sync problems and the different options available to restore proper audio/video alignment.
Common Causes
There are several common causes for streaming audio and video falling out of sync on Android devices:
WiFi connectivity issues can lead to intermittent buffering and delays that throw off sync. This occurs when the WiFi signal is weak or inconsistent. Trying to stream over a crowded WiFi network can also introduce latency and sync problems.
Incompatible codecs between the video file and Android device is another culprit. The video may use an unsupported or outdated codec that the device struggles to decode properly, leading to lag between audio and video tracks. This is most noticeable with older or lower-end Android devices.
Hardware limitations like an underpowered processor or insufficient RAM may make it challenging for the device to decode high bitrate video streams in real time. This can gradually lead to increasing audio/video sync drift.
High resolution streams that max out the device’s capabilities are more prone to sync issues. Lowering video quality settings sometimes helps in these cases.
Problems with the actual video file, such as corruption or an incorrect frame rate, can also throw off AV sync. Trying a different file source may help isolate such issues.
Software Fixes
One common cause of audio and video sync issues on Android is buggy software or app settings. Trying the following software tweaks may help resolve sync problems:
Toggle hardware acceleration in apps – Some video apps like YouTube allow toggling hardware acceleration on/off in the settings. Turning this off can fix sync issues caused by hardware problems.
Clear the app cache/data – Over time, bugs or glitches can build up in the app cache causing sync problems. Clearing the cache and app data for video apps can wipe out these issues.
Update apps – Developers often release updates to fix bugs, so ensuring you have the latest YouTube, Netflix, media player etc versions can resolve lingering audio sync bugs.
Factory reset your device – For stubborn system-wide audio sync problems, a factory reset can wipe out any deep rooted software glitches. Backup your data first.
Contact the developer – If a particular video app has persistent audio sync issues, reporting the problem to the developer may lead to a fix in future updates.
Switch media players – If the sync issue only occurs in one video app, trying a different more stable media player like VLC can avoid the problem.
Hardware Fixes
One potential cause of audio and video being out of sync on Android devices is hardware-related issues. Upgrading to a newer, more powerful device can help if your current device lacks the processing power to properly sync audio and video streams.
Using a wired internet connection rather than WiFi can also help stabilize network connectivity and reduce latency that contributes to sync issues. Ethernet cables provide more reliable bandwidth for high-quality video streaming.
Connecting the Android device to external speakers via Bluetooth or AUX cable can bypass built-in speakers that may be contributing to the sync problem. External speakers receive and play the audio stream separately from the video displayed on-screen.
Checking audio drivers and settings can uncover hardware problems causing the sync issue. Troubleshooting guides recommend updating audio drivers, disabling audio enhancements, or adjusting default sample rates if the Android OS is struggling to output clean synchronized audio.
If hardware upgrades and troubleshooting do not resolve the issue, it likely stems from problems in the content itself or the streaming app rather than the Android device hardware.

Network Fixes
One of the most common causes of audio sync issues is having a subpar network connection when streaming video. The problem often arises when there is not enough bandwidth or the network is unreliable resulting in lag and delays. Switching to a more stable wired Ethernet connection can often alleviate sync problems for streaming content. If using Wi-Fi, try to get as close as possible to the router or access point and eliminate any sources of interference that could disrupt the signal. You can also try changing broadcast channels on the router to reduce congestion.
On Android, going into Settings > Network & Internet > WiFi and tapping on the name of your connected network will bring up advanced options. Here you can see technical details about your connection speed and strength. If the signal strength is weak, try moving closer to the router or access point. You can also go to Advanced and change the WiFi frequency band to 5GHz for reduced interference. Test different channels as well to find the optimal one. Improving your Wi-Fi connectivity in this manner will provide faster, more reliable video streams and reduce chances of audio delay issues occurring.
Codec Fixes
Outdated or corrupted media codecs can sometimes cause issues with audio and video syncing properly. Codecs are used by your Android device to encode and decode audio and video streams. If the codecs are not up to date or become corrupted, it can result in the audio and video getting out of sync.
To check your codecs and update them if needed:
1. Open the Settings app on your Android device.
2. Select “Apps” or “Apps & notifications.”
3. Tap the menu button and choose “Show system apps.”
4. Look for any media codec related apps like “Media codecs” or “Media framework.”
5. Tap on each media codec app and choose “Update” if an update is available.
Updating the codecs may resolve codec corruption issues causing the audio/video sync problem. You can also try clearing data and cache for the media codec apps if updates are not available.
If updating codecs does not work, you may need to factory reset your Android device to fully clear any corrupt codec files as a last resort. Be sure to backup any important data first before resetting.
App Settings
Many streaming apps like Netflix, Hulu, YouTube, and others have settings you can adjust to help fix audio/video sync issues. Here are some tips for common streaming apps:
For Netflix, go to App Settings > Cellular Data Usage and toggle “Limit data usage” off. This prevents Netflix from throttling video quality which can cause sync issues. You can also try clearing the app cache and data in system settings.
In the YouTube app, go to Settings > General and disable “Limit mobile data usage”. This prevents YouTube from lowering quality. Also enable “Disable audio ducking” to prevent audio drops. Clearing app cache/data may help too.
For Hulu, check Settings > Video Quality and select “Best quality”. Turn off “Limit cellular data usage” too. Hulu also has an Audio Offset feature in Settings you can tweak to adjust sync.
Finally, updating the app, rebooting your device, and ensuring you have a strong wifi/mobile data connection can prevent sync problems in many streaming apps.
Contact Developer
If you still have audio/video sync issues after trying the software, hardware, network, codec, and app setting fixes, you may need to reach out to the app developer/support for further assistance. Many streaming and media apps have dedicated customer support teams to help troubleshoot problems.
Before contacting the developer, make sure to note details that could help them investigate:
– App name and version
– Device model
– Android OS version
– When issue occurs (specific shows, movies, etc)
– Steps taken already to resolve
– Any error messages shown
You can typically find customer support contact info on the developer’s website or in the app. Popular streaming apps like Netflix, Hulu, Disney+, and YouTube have online contact forms to submit for tech support. Smaller apps may rely on email or in-app messaging.
Explain the audio sync problem clearly and include any details that could help. The developer can look into potential bugs causing the issue or suggest advanced fixes. If it appears isolated to your device, they may recommend reset steps. Make sure to also update the app if a new version is available, as it may address known bugs.
With help from the app creator, you should be able to resolve even difficult audio/video sync issues that other fixes can’t address. Customer support can provide personalized troubleshooting to get your streaming working properly again.
Factory Reset
As a last resort if no other fix works, you can reset your Android device to its factory settings. This will erase all your data and settings and restore your device to its original state when you first bought it. According to this Google Pixel support thread, a factory reset can potentially resolve audio/video sync issues.
Before factory resetting, make sure to backup any important data, photos, videos, etc. that you want to keep. You’ll have to reinstall all your apps and redo your settings after the reset. Also be aware that this may not necessarily fix the audio sync problem if it’s a deeper hardware or software issue.
To factory reset, go to Settings > System > Advanced > Reset options > Erase all data (factory reset). Follow the prompts to confirm the reset. Once completed, set up and configure your device again. Test your streaming video to see if the audio sync is improved.
Factory resetting should be done cautiously as you may lose data. But if you’ve tried other troubleshooting steps with no success, it may be worth considering as a resolution of last resort.
