Aura Loop – No Sound? Follow These Simple Steps

Can't hear your TV through the Aura Loop earbuds? Follow these steps in order to find where the sound stops.

If You’re Using a Soundbar

If your soundbar uses HDMI ARC/eARC, temporarily unplug its HDMI cable from the TV. Some TVs send audio to only one device at a time. Then play something on the TV and test the Aura Loop again.

Step 1 – Check the Cables & Turn On the Transmitter

Make sure all cables are firmly connected:

Power: USB-C → TV USB or power adapter
Optical: Transmitter OPTICAL → TV Optical Out
AUX: Transmitter AUX → TV Headphone / AUX Out

Important: Use only one audio cable — Optical or AUX. Do not connect both at the same time.

After connecting the cables, turn ON the transmitter.

Step 2 – Check the WHITE Audio Input Light

Check the Audio Input light on the transmitter.

Solid WHITE → Good! The TV is sending a valid audio signal. Go to Step 4.

No WHITE light → The transmitter is not receiving TV audio. Go to Step 3.

Step 3 – Check the TV Audio Settings

Using an Optical Cable?

Sound Output → Optical / Digital Audio Out
Digital Audio Format → PCM

Can't find these settings? Choose your TV brand in our guide.

Find Your TV's Optical / PCM Settings

Using a 3.5mm AUX Cable?

Set your TV audio output to Headphones / Audio Out, then turn up the TV volume.

Step 4 – Check the Earbuds

Solid WHITE = Valid TV audio signal. Audio is reaching the transmitter, so there should be sound once the earbuds are connected.

Turn ON both Aura Loop earbuds and wait a few seconds for them to connect.

Solid ORANGE = Earbuds connected through Auracast

If the transmitter is solid WHITE and the earbuds are solid ORANGE, you should hear the TV audio.

Step 5 – Still No Sound? Check the Volume & Try Another Program

Press + on the earbuds several times. If using AUX, also turn up the TV volume. If using Optical, press Volume Boost on the transmitter once.

Still no sound? Try another TV channel, video, movie, or app. If only some programs have no sound, make sure the TV's Digital Audio Format → PCM.

Something Doesn't Look Right?

Solid WHITE Light but Still No Sound?

Solid WHITE confirms the TV is sending a valid audio signal to the transmitter. Check that the earbuds are connected and the volume is turned up.
