YouTube TV (YTTV) will have out-of-sync audio if the sound settings of the device are not as per the requirements of the YTTV or if there is a resolution mismatch between your device and the display unit.
The issue is reported on all platforms supported by YTTV including streaming, Android, iOS, consoles, TVs, Windows, Mac, browsers, etc. Sometimes the audio is ahead of the video and at other times, behind the video. In some cases, the issue worsens with time. For some people, only local channels are affected.
Before beginning the troubleshooting:
- Make sure your Internet speed meets the YouTube TV requirements. For example, you will need 20 Mbps speed for 4K UHD. You may have a better connection than the required one but the actual speed may be less, so, taking a speed test will confirm the case.
- Check if the audio issue is occurring on a supported device. For example, HomePod is not a supported device.
- If the issue is occurring on a browser, check if the TV works properly in another browser.
- Open settings, forward, rewind, or switch the channel on YouTube TV and check if the issue is temporarily cleared.
1. Force Close the YouTube TV App or Browser
The audio on YouTube TV will be out of sync if the app’s audio modules are failing to utilize the device’s audio resources in real time. Here, relaunching the YTTV app after force closing it will do the trick as the communications will be reestablished.
On an iOS device, open the App Switcher and swipe up the YouTube TV app.
On an Android device:
- Open the App Switcher and tap on the cross icon for the YouTube TV app.
- Launch the device’s Settings and go to Applications > YouTube TV.
- Tap on Force Close and confirm to close the app.
- Launch YouTube TV and see if the audio problem is solved.
If the problem is occurring on a browser, relaunch the browser and check if the issue is cleared.
2. Restart the Device
YTTV audio might be out of sync if the output modules of your device or system are not in a state required by YouTube TV. Here, restarting the device or system will resolve the audio issue.
Restart Through the Device Menu
For a Roku:
- Launch the Roku Settings and go to System.
- Select System Restart > Restart and then check if the audio issue is resolved.
- If not, restart your TV (if applicable) from its menu and check if the problem is solved.
In the case, the issue is occurring on a Windows PC, disable its Fast Startup (Control Panel > Power Options > Choose What the Power Buttons Do > Change Settings That Are Currently Unavailable > uncheck Turn on Fast Startup) and then restart the system. Check if the problem is solved.
Cold Restart Your Devices
- Power off your streaming device (or phone/PC) and unplug its power cable.
- Switch off your TV and unplug its power cable.
- Power off your router and unplug its power cable.
- Wait for a minute and plug back everything.
- Power on your router and then the TV/steaming device. Verify if the YouTube TV is operating correctly.
3. Clear the Cache of the YouTube TV App (Android Only)
YTTV audio will be out of sync if its cache is no more valid and as a result, the app is failing to properly utilize it. To fix this, clear the cache of the YouTube TV app.
- Launch Settings of your Android device and go to Applications > YouTube TV.
- Open Storage and tap on Clear Cache.
- Restart your device and check if the YouTube TV app is clear of the audio issue. In the case of a streaming stick such as a Firestick, remember to restart the device through its menu.
4. Update the YouTube TV App and the Device’s OS
You will get out-of-sync audio on the YTTV app if the app or your device’s OS is outdated. This can cause several issues as the outdated OS will fail to comply with the latest communication protocols.
This can be solved by updating the YouTube TV app and the device’s OS to the latest releases.
Update the YT TV App
On an iOS device, use the Apple App Store to update the YouTube TV app.
- Launch Play Store and search for YouTube TV.
- Update the YT TV app (if available) and restart the device. Check if the audio problem is solved.
Update the Device’s OS
For an iOS device, navigate to Settings > General > Software Update. Install the update and see if the problem is solved.
For an Android device:
- Go to Settings > Software Update.
- If an update is available, install it and restart the device. Verify if the audio sync problem is solved.
5. Reinstall the YouTube TV App
If the latest update to the YouTube TV app failed to be properly applied to the audio modules of the current installation, the audio sync issue may arise. This can be solved by reinstalling the YouTube TV app.
To do so on an Android device:
- Go to Settings > Applications > YouTube TV.
- Uninstall the app and power off the device.
- Unplug its power cable and wait for a minute.
- Plug back the power cable and power on the device.
- Reinstall the YouTube TV app and launch it.
- Log into the app and determine if the audio is no more out of sync.
6. Change the Device’s Resolution
If your device’s resolution does not match the display resolution, the video may be parsed more quickly or more slowly than the audio and thus cause the out-of-sync audio. To solve this, change the device’s resolution.
To change the display resolution on a Fire TV:
- Go to Settings > Display & Sounds > Display > Video Resolution.
- Set it to Auto and see if the audio is syncing properly on YouTube TV.
- If not, change the screen resolution to 720p and check if that clears the problem. You can also try other resolutions one by one.
For an Apple TV, change the picture quality to 4K HDR and verify if the audio issue is resolved.
7. Disable Hardware-Accelerated Video Decode Flag (Chrome Only)
If the Hardware-accelerated video decode is enabled in the Chrome settings, it can speed up the video decoding and as a result, the audio may lag. In such a case, disabling the Hardware-Accelerated Video Decode Flag will solve the problem.
- Launch Chrome and enter the following in the Address Bar:
- Expand the dropdown of the feature and select Disabled.
- Relaunch the browser and check if the YouTube TV is operating correctly.
Remember, this flag may also work for other browsers based on Chromium (such as Brave).
8. Reinstall the System’s Audio Driver (Windows Only)
YouTube TV audio will be out of sync if the core modules of your system’s audio driver are no more valid or compatible with the YTTV. Reinstalling the system’s audio driver will do the trick here.
Before starting, download the latest audio driver from the OEM website.
- Right-click on Windows and select Device Manager.
- Expand Sound, Video, and Game Controllers and right-click on your audio device.
- Select Uninstall Device and tick the option of Attempt to Remove the Driver of This Device.
- Click on Uninstall and once done, restart the system.
- If Windows tries to install a generic driver, let it complete and check if the audio sync issue is resolved.
- If not, uninstall the audio driver again and restart the system.
- Install the downloaded audio driver as an administrator and restart the system. Check if the YouTube TV audio sync problem is solved.
