If only one language or commentary track is delayed, the source track timing can be the relevant issue. Do not apply a global TV delay that misaligns every other programme. Compare the available tracks and report the affected one with a timestamp. Compare the alternate and main track at the exact same audiovisual cue without changing speakers or output processing. If only the alternate track differs, keep the investigation local to that track instead of shifting the entire TV and making the main mix wrong.
Keep the comparison local
Use the same title and scene. Replay a clear spoken line, clap or other visible cue and switch only the audio track. Check the exact track labels, since commentary may describe action rather than correspond directly to it. A dubbed line can also have different wording without necessarily being a timing fault. Use a cue that legitimately should align, and record whether the alternate track leads or follows the picture while the ordinary mix stays aligned through the same equipment.
Check constant or drifting offset
Those symptoms need different treatment. Check the alternate track near the start and later in the item. A stable offset may be handled by a supported track-specific adjustment, while a growing gap points toward timing-rate or timestamp problems. A sudden mismatch after an added scene suggests an edition or transition issue. Record the pattern before changing anything so the operator can distinguish a simple initial track offset from a fault that cannot be repaired by one fixed delay.
Use per-track correction where supported
Avoid a permanent whole-system adjustment for one asset. Use a local track or title correction only where the application documents it, and preserve the original value. If only a global delay is available, consider using a correctly aligned supplied track while reporting the affected one rather than breaking every other title. Include the edition, exact track label, cue timestamp and observed direction. A precise report helps identify the source audio timing without requiring private account data or broad hardware resets.

An example to work through
English audio aligns while another supplied language starts consistently late in the same edition. The main mix aligns with a door closing, while the alternate language track consistently follows it later on the same speakers. This comparison isolates a track-specific timing difference more effectively than changing Bluetooth settings that would also shift the already aligned main audio.
Questions about this topic
Is this automaticallyBluetooth lag?
Not if the same output aligns with another track. A shared output that aligns with the main track makes a track-specific timing issue worth checking.
Should all system audio be shifted?
Usually not for one source track. Keep corrections local where possible so correctly aligned media remains usable.
