Orbit Pro - Fix No Sound

  • Updated
No sound from your Orbit Pro usually means the wrong operating mode or audio input is selected, the TV is not sending a valid audio signal, or your Bluetooth headphones are not connected. Follow these 3 steps in order.
1

Check TX Mode and the TV Audio Connection

  1. Make sure Orbit Pro is powered on.
  2. Slide the operating mode switch to TX (Transmitter).
  3. Check which cable connects your TV to Orbit Pro.
  4. Set the audio input selector to OPT, AUX, or HDMI, matching the cable you are using.
  5. Play a TV program with sound.
Important: Use TX when sending TV audio to Bluetooth headphones. RX is for receiving Bluetooth audio from a phone or other source and sending it to a wired speaker.
I'm Using an Optical Cable
TV — OPTICAL / DIGITAL AUDIO OUT ↓ Optical Cable ↓ Orbit Pro — OPTICAL INPUT
  1. Connect the TV's Optical / Digital Audio OUT to Orbit Pro's Optical INPUT.
  2. Set the Orbit Pro input selector to OPT.
  3. Open the TV's sound settings.
  4. Select Optical / Digital Audio Out as the sound output, if required.
  5. Set the TV's digital audio format to PCM / Stereo.
  6. Play audio again.
Important: Dolby Digital, DTS, Bitstream, or Auto may prevent Orbit Pro from receiving compatible audio.

I'm Using HDMI ARC
TV — HDMI ARC / eARC PORT ↓ HDMI Cable ↓ Orbit Pro — HDMI ARC INPUT
  1. Connect the HDMI cable to the TV port labeled ARC or eARC.
  2. Connect the other end to Orbit Pro's HDMI ARC connection.
  3. Set the Orbit Pro input selector to HDMI.
  4. In your TV settings, select HDMI ARC / Receiver / External Speaker.
  5. Set the digital audio output to PCM / Stereo.
  6. If your TV offers an eARC setting, turn it OFF and test standard ARC.
  7. Play TV audio again.
Important: HDMI ARC requires the TV's designated ARC/eARC port. A regular HDMI input cannot be used as the TV's ARC audio output.
I'm Using AUX / 3.5 mm or RCA
TV — HEADPHONE / AUDIO OUT ↓ 3.5 mm AUX or RCA-to-AUX Cable ↓ Orbit Pro — AUX INPUT
  1. Connect the TV's Headphone / Audio OUT to Orbit Pro's AUX INPUT.
  2. Set the Orbit Pro input selector to AUX.
  3. Select the TV's headphone or analog audio output if required.
  4. Increase the TV's headphone output volume.
  5. Play audio again.
Note: PCM settings are generally not required for analog AUX connections. If using RCA, connect to Audio OUT, not Audio IN.

Check the Audio Signal Indicator

While the TV is playing audio, look at Orbit Pro's red audio-signal indicator.

Solid Red

Orbit Pro detects a valid audio signal. Continue to Step 3.

Flashing Red

No valid audio signal is detected. The indicator flashes about once per second.

Flashing Red? Fix the TV Audio Signal
  1. Confirm the TV is playing a program with sound.
  2. Check that the Orbit Pro input selector matches your cable: OPT, AUX, or HDMI.
  3. Disconnect and firmly reconnect the cable at both ends.
  4. Make sure the cable runs from a TV audio output to the Orbit Pro input.
  5. For Optical or HDMI ARC, set the TV audio format to PCM / Stereo.
  6. For AUX, increase the TV's headphone output volume.
  7. Check whether the red indicator becomes solid.
No Sound Only on Netflix or Other Streaming Apps?

If regular TV channels work but Netflix, Prime Video, Disney+, or another streaming source does not, the source may be sending an incompatible digital audio format.

  1. Start playing the affected video.
  2. Open the TV or streaming device's audio settings.
  3. Change the digital audio format to PCM / Stereo, when available.
  4. Restart the video and test the sound.

Expected: The red audio-signal indicator stays solid, confirming that Orbit Pro is receiving TV audio.

Check the Bluetooth Headphone Connection and Volume

Orbit Pro has an LCD screen that displays the Bluetooth device name, connection status, selected input, and volume level.

What to Check on the LCD Screen

TX mode selected
Correct input: OPT / AUX / HDMI
Headphone name displayed
Bluetooth status: Connected
Volume level above minimum

  1. Confirm Orbit Pro is in TX mode.
  2. Look for your headphone name and a Connected status on the LCD screen.
  3. If your headphones are not connected, open the pairing instructions below.
  4. Increase the volume on your Bluetooth headphones.
  5. Use Orbit Pro's volume controls to raise its output level if needed.
  6. Play TV audio again.
Headphones Not Connected? Pair Them Again
  1. Keep Orbit Pro in TX mode.
  2. Temporarily turn off Bluetooth on nearby phones, tablets, or computers that your headphones may reconnect to.
  3. Put your headphones into Bluetooth pairing mode.
  4. On Orbit Pro, short-press the Search button to search for nearby Bluetooth devices.
  5. Use the menu controls to locate your headphone name on the LCD screen.
  6. Select the headphones to connect.
  7. Wait until the LCD screen shows Connected.
Tip: Simply turning on Bluetooth headphones does not always put them into pairing mode. Follow the headphone manufacturer's pairing instructions.
My Headphones Are Listed but Not Connected
  1. Check that the headphones are powered on.
  2. Disconnect them from any nearby phone, tablet, or Smart TV.
  3. Use Orbit Pro's LCD menu to select the headphone entry.
  4. Press the device selection control to connect.
  5. Wait for the LCD to display Connected.
Important: Seeing a headphone name in the device list does not necessarily mean it is currently connected. Check the LCD connection status.
Headphones Connected but Volume Is Too Low?
  1. Increase the volume directly on your headphones.
  2. Press Orbit Pro's Volume + button to increase its volume.
  3. Check the volume level shown on the LCD screen.
  4. If using AUX, also increase the TV's headphone output volume.
  5. Test a program with clear speech.
For hearing aid users: If volume adjustment does not work with your compatible hearing aids, see the dedicated Orbit Pro volume adjustment guide in the product support section.
Expected: Orbit Pro is in TX mode, the audio-signal indicator is solid red, the LCD shows your headphones as Connected, and sound plays through them.
Still Not Connecting? Clear the Pairing History

Try this only if your headphones will not reconnect after normal pairing attempts.

  1. Make sure Orbit Pro is powered on.
  2. Press and hold Volume + and Volume − together for 5 seconds.
  3. Wait for the saved Bluetooth device entries to disappear from the LCD screen.
  4. Put your headphones into Bluetooth pairing mode again.
  5. Use Orbit Pro's Search button to find and reconnect them.
Important: This reset clears saved Bluetooth pairing history. It is not usually necessary when the problem is caused by incorrect TV audio settings.

Headphones Work but My Soundbar Has No Sound

If you are also using a wired soundbar, check the Orbit Pro pass-through connections.

  1. Confirm the TV cable is connected to Orbit Pro's INPUT.
  2. Connect the soundbar to the corresponding OUTPUT.
  3. Use matching connection types: Optical IN to Optical OUT or AUX IN to AUX OUT.
  4. Set the soundbar to its matching Optical or AUX input.
  5. For Bluetooth headphone listening, keep Orbit Pro in TX.
Important: Orbit Pro's wired pass-through does not support HDMI ARC input to a soundbar output.
