How to Fix Echo When TV Speakers and Hearing Aids Play at the Same Time？

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.

Cause

When audio is played through two output paths at the same time, a delay difference may occur:

• TV speakers play audio almost instantly

• Auracast audio (to hearing aids or receivers) has a small, unavoidable transmission delay

If the TV has additional audio processing or voice enhancement features enabled, this delay difference becomes more noticeable, resulting in echo.

Support Notes

If echo still occurs, consider using an external wired speaker connected to an Auracast receiver instead of TV speakers to avoid delay or echo.
