Soundjet R2 - Fix No Sound – Avantree Support

No sound from SoundJet R2 is usually caused by disconnected Bluetooth headphones, an incorrect AUX/USB audio connection, or low volume. Follow these 3 steps to fix the problem.

Check the Bluetooth Headphone Connection

Flashing red and blue LEDs mean your headphones are not connected and may still be connected to another device, such as your phone.

Turn on SoundJet R2 and your Bluetooth headphones. Check the connection status before testing the sound.

Headphones Connected

If your headphones are connected, continue to Step 2.

Flashing Red & Blue

Pairing mode is active. Follow the steps below to connect your headphones.

If Your Headphones Are Not Connected

Turn Bluetooth OFF on nearby phones, tablets, or computers that your headphones may reconnect to.
Put your headphones into Bluetooth pairing mode. Simply turning them on may not activate pairing mode.
Put SoundJet R2 into Bluetooth pairing mode using its multifunction control.
Keep SoundJet R2 and your headphones close together and wait for the connection to complete.
Once connected, play audio to test the sound.

Headphones still won't reconnect? Reset SoundJet R2 by turning it on and quickly double-clicking the Multifunction Button (MFB). The red and blue LEDs will illuminate together for approximately 3 seconds (appearing pink), then flash red and blue. Put your headphones into pairing mode and reconnect them. This clears previously saved Bluetooth connections.

Once your headphones are connected, continue to Step 2.

Check the Audio Source Connection

SoundJet R2 must receive audio from the correct 3.5 mm AUX output or a compatible USB audio source; an incorrect port or unsupported USB cable can prevent sound.

Follow the instructions for how you're using SoundJet R2.

Airplane

Plug SoundJet R2 into the airplane seat's 3.5 mm headphone output. If the seat has a compatible dual-prong socket, use the appropriate airplane adapter.

Start a movie or music on the seat screen and increase the screen's volume.

TV / AUX

Connect SoundJet R2 to the TV or audio source's Headphone / Audio OUT port.

Make sure the connector is fully inserted, select the headphone output in the TV settings if required, and increase the source volume.

Do not connect to AUX IN or a microphone input.

Windows PC

Connect SoundJet R2 to a compatible USB port using a USB data/audio cable.

Go to Settings > System > Sound. Under Output, select Avantree SoundJet R2.

Make sure the output is not muted, increase the volume, and play audio.

SoundJet R2 Computer Troubleshooting

Computer not detecting SoundJet R2? Try another compatible USB data/audio cable and another USB port. A charging-only cable may supply power without transmitting audio.

Once your audio source is connected and playing, continue to Step 3.

Check the Volume and Test the Sound

Even when SoundJet R2 and your headphones are connected, muted or low volume on the audio source or headphones can prevent you from hearing sound.

Play a movie, video, or music track and make sure the audio source is not muted.
Increase the volume on the airplane screen, TV, computer, or other audio source.
Increase the volume on your Bluetooth headphones or earbuds, if supported.
If your headphones have separate volume controls, check those as well.
Play a familiar video or music track again to confirm whether the sound is working.

Still no sound? Test with another pair of Bluetooth headphones or another compatible audio source, if available. This can help identify whether the issue is with the headphones or the audio connection.
