You may hear an echo when using Auracast with hearing aids or an Auracast receiver while the TV speakers are also enabled.
Cause
This is a normal behavior when audio is played through two different output paths at the same time:
TV speakers play audio almost instantly
Auracast audio (to hearing aids or receivers) has a small, unavoidable transmission delay
If the TV has audio enhancement or sound processing features enabled, the delay difference becomes more noticeable and can cause an echo.

Support Notes
Menu names may vary by TV model and region
Always recommend Standard / Normal sound mode as the first troubleshooting step
This behavior may occur across different TV brands and models
If echo still occurs, consider using an external wired speaker connected to an Auracast receiver instead of TV speakers to avoid delay or echo.
