Fix TV & Hearing Aid Echo – Avantree Support

Echo happens because TV speakers play sound instantly, while Auracast audio to hearing aids has a small delay. When both play together, the timing difference creates an echo.

Quick Check

1. Lower TV volume – Reduce TV speaker volume and increase hearing-aid volume.

2. Turn off TV sound effects – Set your TV to Standard / Normal / Original and disable any sound effects or processing (Voice Enhancement, AI/Adaptive Sound, Surround, Dolby/DTS) that can delay audio and cause echo.

3. Check TV audio settings – Look for Audio Delay / AV Sync and adjust it slightly if you see the option.

4. Try turning off TV speakers – If echo continues, listen through hearing aids only.

5. Restart devices – Restart the TV and transmitter if it still doesn’t work.

If it still happens, consider connecting a wired speaker to an Auracast receiver so both receive the same audio at the same time. Learn More Here:

Why This Happens

Auracast hearing aid audio is slightly delayed compared with the TV speakers, and extra TV sound processing makes that delay more noticeable.

💡 Tip:

Many users keep the TV speakers muted and adjust the volume on their hearing aids or transmitter instead.
Avoid These Sound Modes

❌ Clear Voice / Voice Enhancement
❌ AI Sound / Adaptive Sound
❌ Clear Dialogue
❌ Surround / Virtual Surround
❌ Dolby or DTS audio processing

These sound effects can change the audio format or add processing that may cause no sound, delay, or connection issues.
