Roku has introduced an Adjust audio delay tool within its mobile app to correct lag between television video and Bluetooth audio. The feature uses your phone's camera and microphone to synchronize sound for households using wireless or wired headphones for private listening.
Why it matters
Bluetooth processing and home network transmissions often cause audio to fall behind video, creating a frustrating viewing experience. This tool allows viewers to manually or automatically align sound to improve the home theater experience.
The new tool supports up to four simultaneously connected listening devices. The process functions with both wired earbuds and Bluetooth headphones paired to a mobile device.
The players
Roku
A developer of streaming media players and smart home technology known for its user-friendly interface.
The details
To calibrate the sync, the app uses your phone's camera and microphone to observe the television screen and monitor room audio for timing mismatches. Users must grant the app access to these sensors and ensure the mobile device is on the same Wi-Fi network as the Roku hardware. If the automatic test requires further refinement, an advanced slider allows for manual adjustments to the audio delay.
Timeline
September 27, 2026: The tool's availability is reported.
The Home Front
This update follows a pattern set by the Bluetooth A2DP audio profile latency limitations, which frequently force manufacturers to develop software-based synchronization workarounds. It marks a departure from hardware-dependent solutions by shifting the calibration burden to a personal mobile device.
Check your mobile app store for an update to the Roku app to access the new audio calibration settings. Ensure your phone and Roku device are connected to the same Wi-Fi network before attempting the sync test.
The takeaway
Using software to bridge the gap between network-transmitted audio and video is a practical way to resolve common streaming delays. Keep your mobile app updated to take advantage of these new calibration features for your private listening sessions.
