No Sound On Foxtel iQ4 – Quick, Effective & Easy Solutions!

Note: First, we recommend checking whether the audio problem appears on all channels or only on one broadcast since the issue may not be with the TV box. 

1. Power Cycle the iQ4 TV Box

The power cycle is considered one of the best-working methods against software or hardware functionality errors with streaming appliances, such as your iQ4.

The electrical circulation can be achieved by unplugging the A/C adapter, which won’t erase anything, only refresh the OS.

Here’s how to conduct a power cycle on the Foxtel iQ4 in easy steps:

1. Hold the Power button on the front panel of the iQ4.
2. Once the box has shut down, unplug the power cable.
3. Wait for 60 seconds while your iQ4 is disconnected.
4. Re-attach the power adapter into an electrical outlet.
5. Turn on the Foxtel cable box and test the functionality.

Tip: While unplugged, check the power adapter for any faults!

2. Correct IQ4’s Digital HDMI Output

There could be an issue with IQ4’s HDMI audio, causing issues with the audio playout of your broadcasts.

It is possible to address issues with the audio output by correcting the HDMI Digital Audio Output format within the iQ4 cable box settings.

Here’s how to correct the digital HDMI audio output on your iQ4 box:

1. First, press the “Home” button on the cable box’s remote control
2. Go to “Advanced Settings” → “Audio and Language Settings.”
3. Select “HDMI Digital Audio Output” from your available options.
4. Then, if applicable to your options, make the following changes:

• If the output is in the “MPEG” format, set it to “AC3.” 
• If the output is in the “AC3” format, set it to “MPEG.”

Note: If there is still no sound after correcting the digital audio format, revert the option to its previous setting before testing any further solutions.

3. Optimise the HDMI Connection Link

There could be a fault with the physical HDMI connection between the TV and the iQ4 cable box, causing interruptions in the video or audio broadcast.

To correct the audio functionality problem, it is advised to perform several adjustments.

iQ4 HDMI Connection Optimisation
Solution:	Instructions:
Reseat the HDMI Cable	Disconnect the HDMI cable from the back of the iQ4 box and the TV for 30 seconds.
Use an Alternative Port	Connect the HDMI cable of the iQ4 box to a different TV port and alter the input source.
Deactivate “HDMI-CEC”	Go to Settings → “HDMI-CEC” and deactivate the feature to display iQ4.
Replace the HDMI Cable	Install a different HDMI cable and attempt to transfer the audio broadcast of the IQ4 to your TV.

Note: Don’t forget to inspect the connectors of your HDMI cable for any damage!

4. Specify the Default Audio Output

If you’ve selected a default audio output that isn’t connected to your TV or isn’t supported by the system, none of the iQ4 channels will have an output.

To correct the fault, you need to navigate into your TV’s settings and specify a relevant and working default audio output for your system.

The iQ4 will output audio through the default audio device selected in your TV’s settings, so there is no need to search for the option in the iQ4 system.

How to Change Audio Output Device In TV Settings?

1. Open your TV’s “Settings” tab and navigate to “Audio.”
2. Select “Default Output Device” and go down the menu.
3. Tap on “TV Speakers” or choose a third-party device.
4. Lastly, save the changes and test the volume of the iQ4.

Alert: Do not select audio devices that are not connected to your TV physically or wirelessly!

5. Reconnect iQ4’s Service Cable

Foxtel set-top-boxes can use satellite service via dish or direct cable connection from a master service socket.

An improper satellite connection might cause an issue with the audio output, so reinstalling the cable is required to restore the volume of the broadcasts and all service media.

Here’s how to identify and reconnect the service cable in easy steps:

1. Locate the “Coax IN” or “SAT IN” socket on the iQ4 box.
2. Unplug the Coaxial service cable from the iQ4 TV box.
3. Wait 30 seconds while your service cable is unplugged.
4. Install the Coaxial cable back into iQ4’s service socket.
5. Test multiple broadcasts available in your Foxtel lineup.

While the service cable of the IQ box is disconnected, inspect its physical condition for rips, cuts or other damages.

If you identify any issue with the service cable, be confident that this is causing your audio loss problems.

Tip: Verify that the cable is secured into the iQ4 TV box’s input port.

6. Unplug Any External Devices

Perhaps the external audio device specified in your TV system as the default output device may not function properly or recognise the connection of the iQ4.

So, the next step is to unplug all the third-party devices from your TV and specify the TV speakers as the default output device.

• Unplug all audio devices connected via Bluetooth, HDMI-ARC, or RCA.

In addition, verify there are no other cable boxes besides the iQ4 connected to your TV system.

When everything is unplugged, refer to solution #2 from earlier in the guide and select your TV speakers as a default audio output.

Note: When your TV speakers are the default audio output, you must increase the TV’s volume!

7. Use the Foxtel “Sound Issues” 

The Foxtel no sound iQ4 issue can be addressed using the equipment troubleshooting tool available on Foxtel’s website.

You will be prompted to select the type of Foxtel equipment to specify the audio issue you’re experiencing.

2. Select the type of audio problem you’re facing.
3. Choose the output device you’ve linked to iQ4.

8. Restore iQ4 to Factory Defaults

Restoring all system settings to factory default and uninstalling all third-party content from iQ4 is another substantial method to resolve the audio issues.

The factory restoration comes with a great downside–this method will delete all of your personalised settings and configurations.

Follow these steps to perform a factory reset on the Foxtel iQ4:

1. Press the “Home” button on your iQ4 remote control.
2. Highlight and select the “Settings” icon on the screen.
3. Navigate to “Advanced Settings” within the system.
4. Input the “0-6-1-1” numbers on the remote’s keypad.
5. Press the “Select” button and go to “Installer Setup.”
6. When prompted, input the default “1234” Foxtel PIN.
7. Follow the on-screen steps to finalise the restoration.

Note: Once the reset is complete, the initial setup of the Foxtel iQ4 is to establish all settings and tune all satellite or cable channels again.

Quick Recap:

Whenever there is no sound on Foxtel iQ4, power cycle the cable box and disconnect all external devices.
