Sound and video out of sync | Lifestyle® 525 series II home entertainment system
Check for audio delay / sync settings in menu of the TV or other connected devices.
Many TVs or video devices (i.e. streaming media box or Blu-ray player) have audio settings, including an audio delay setting. Check for this setting in the menu of the TV and/or the device playing the video and, if available, adjust the setting.
Try playing something else to check if the issue is related to certain media.
Play different content on your system (i.e. a different channel or DVR recording) to determine if the issue is related the content.
Reset your product.
Much like rebooting a smartphone, your product might need to be reset on occasion to correct minor issues. For more information, see Resetting your product.
Try a different app.
If the issue only occurs with a particular app, it is likely related to the app or app settings.
If grouping multiple Bose systems, check if a Wi-Fi network extender or repeater is in use.
Bose systems that you want to play in sync as a group might play out of sync if some systems in the group are connected to a wireless range extender and others are connected to your router. Since the extender receives and then re-broadcasts signal from the router, systems connected to the extender could receive signal later than those receiving signal directly from the router. To avoid this for systems beyond the range of the router, connect them directly to the router with an Ethernet cable (if possible). Otherwise, try repositioning the systems or router so they all connect either to the router or to the extender.
Plug in to a different input on the TV.
Plug in to a different input section on the back of the TV using the same cable(s) to determine if the input is the issue. Whichever section you connect to, select the same input using the TV or remote control buttons to hear and/or see the device (e.g. if you connect to HDMI 3, select HDMI 3 using the TV or remote buttons).
Check for and install any available updates for the TV.
Updates often improve product features and stability. Many TV are updateable via an Internet connection or a USB connection. For Internet-connected TVs, look for an Update option in the TV menu. If the TV does not have an Internet connection, look for update instructions on the manufacturer's website or contact customer service for the TV.
