Auracast Audio Sync Guide

Will Auracast Stay in Sync with My Home Theater Speakers?

The most important factor is how the audio is routed. Using the same audio output path gives both systems the most consistent timing.

Best Setup: Use the Same Audio Output Path

Feed both your home theater speakers and the Auracast transmitter from the same digital audio output whenever possible.

Same Path vs. Different Paths

Different devices can process audio at different speeds, which may create a slight delay, echo, or lip-sync difference.

Recommended: Same Audio Path

Both systems receive audio from the same source path.

Same Digital Audio Output

Home Theater Receives the same audio feed

Auracast Transmitter Receives the same audio feed

May Be Out of Sync: Different Paths

Each audio path may add a different amount of processing.

TV / Source

A/V Receiver / HDMI / Wi-Fi → Speakers

TV / Source

Optical Output → Auracast Transmitter

Different processing paths can create a noticeable timing difference.

For the Most Reliable Sync

Use the same digital audio output for both systems whenever possible.
Examples include the same Optical (TOSLINK) or HDMI eARC audio path.
Avoid sending your speakers and Auracast transmitter through different audio paths if you hear echo or delay.

What Auracast Cannot Correct

Processing delays inside your TV or A/V receiver
Timing differences between HDMI, Wi-Fi, optical, or other separate audio paths
Delay caused by mismatched audio routing

Hearing an Echo?

Some TVs and receivers have an Audio Delay, AV Sync, or Lip Sync setting that may help. Results vary by system.

Bottom Line

Auracast sync depends mainly on your audio routing and signal chain. Keeping both systems on the same audio path gives the most consistent result.
