NO SOUND TROUBLESHOOTING

Ensemble Pro – No Sound From Headphones?

Follow these steps if your Ensemble Pro (HT5150R) is connected to your TV but you cannot hear sound.

Before You Start: Play a TV channel or video that has sound. Keep it playing while checking the settings below. You do not need to factory reset your headphones.

Step 1 – Check the TV Audio Cable

Check the cable connecting your TV to the Ensemble Pro transmitter / charging dock.
Make sure it is firmly connected at both ends.
Select the matching audio input on the transmitter:
- OPT – For an Optical cable.
- AUX – For a 3.5 mm audio cable.

Tip: Optical is recommended if your TV has an Optical Audio Out port.

Step 2 – Check Your TV Audio Settings

Open the section that matches your cable connection.

Using an Optical Cable (Recommended)

Press Quick Settings or Home on your TV remote.
Open Settings → Display & Sound → Audio Output.
Find Digital Audio Out.
Set Digital Audio Out → PCM.

Can't find the PCM setting? TV menus vary by brand and model.

Find PCM Settings for Your TV Brand →

Using an AUX / 3.5 mm Cable

Connect the cable to your TV's Headphone / Audio OUT jack.
Select Headphones / Audio Out in the TV sound settings if required.
Increase the TV volume and make sure it is not muted.

Step 3 – Check the Transmitter's Input Signal

Keep your TV program or video playing.
Look at the Input Signal indicator on the transmitter.

Steady signal indicator: The transmitter is receiving audio. Continue to Step 4.

Flashing / no signal: Recheck the TV audio output, PCM setting, and cable connection.

Step 4 – Check the Headphone Connection

Turn on the Ensemble Pro headphones.
Wait for the headphones to connect to the transmitter's Auracast broadcast.
Check the headphone indicator light.

Solid Orange – Connected to Auracast

If the headphones are still searching, turn them off and back on near the transmitter, then wait for the connection.

Important: For normal TV listening with the included transmitter, use Auracast. You do not need to pair the headphones through your TV's Bluetooth menu.

Step 5 – Check the Volume

Press Volume + on the headphones to increase the sound.
If the volume is still too low, locate the Volume Boost switch on the transmitter.
Slide it from Normal to High if more volume is needed.

Only Certain Apps or Channels Have No Sound?

If regular TV audio works but Netflix, Prime Video, a streaming stick, or a cable box does not:

Open the TV or streaming device's audio settings.
Change the digital audio format to PCM or Stereo when available.
Play the program again to test.
