Sound and video out of sync | Bose SoundLink Home Bluetooth Speaker
With certain source devices and/or apps, a slight audio/video delay when using Bluetooth audio is normal.
Wireless audio connections can introduce a slight delay, which becomes noticeable when watching videos. Bose speakers and systems include technology designed to keep audio and video in sync. However, for this feature to work, the connected device (and app, if used) must also support the same syncing technology. If the source device or app doesn't support it, you may experience a slight mismatch between the audio and video.
