So without any further ado, let’s get into it.

How to fix JBL Quantum 100 with no sound problem?

Check whether the mute is turned off or not:

You might have muted your speaker entirely, and all your attempts to play any sound won’t ring to any avail then. So you must ensure that your speaker is not muted at all.

  • Go to your desktop.
  • Click on the speaker icon at the bottom right corner of your screen.
  • Check whether the slider on it is set to a minimum value. If it is set to a minimum, turn it to the highest possible setting here.

Now try playing any sound through your JBL Quantum 100 headphones. If you still don’t hear anything, try the next fix.

Reconnect your headset:

It is also possible that your system did not register your headphones when you plugged them in. It might be due to any software glitch in the device recognition mechanism of your system. So disconnect your headphones from your system entirely and then plug in the audio jack back into the system’s designated port.

If reconnecting the headphones does not solve your problem, try the next solution.

Reboot Your Device:

In some rare scenarios, simple system bootup could be the issue behind your issue. Maybe when your system booted up this time, it did not load its drivers properly. So click on the start button on your PC and choose the Power options. Please select the option restart and wait until the computer restarts.

After the restart is complete, try using the headphones again. Try the next solution if it does not get any sound output.

Update the OS:

Microsoft pushes out updates to Windows regularly to fix its issues. You should also try updating your Windows 10 to the latest version to set your error.

  • Press Windows Key + I to open up Windows Settings.
  • Click on “Update & Security.”
  • Now, click on the Windows Update tab, and you will see the Windows update option in the right pane.
  • If you see a pending Windows update, install it on your computer.

Similarly, you can try updating your Mac or Linux system to the latest version and check whether that solves your problem.

If updating the operating system to the latest version does not help with the JBL Quantum 100 audio output issue, try the next solution mentioned below.

Check for external damage:

The headphones come with a cable that needs to be connected to the system to work correctly. If there is any wear or tear in the cable, your computer will have a tough time producing the desired output on the headphones. So check the cable properly and see if there is any visible damage. If there is no physical damage, move on to the next solution. But if there is any visible damage, change the cable of your headphones and connect them to your PC again. It should work this around.

Disable Audio Enhancements:

Windows has a built-in audio enhancement tool that emphasizes the sound quality as much as possible and customizes it to the end user’s liking. But in some cases, these enhancements might not be compatible with the JBL device. Here, it is the Quantum 100 headphones.

So if you have the audio enhancement feature turned on in your system, disable it entirely and check whether that resolves your problem.

  • Open up the Control Panel and choose the option Sound.
  • Here, click on the Playback tab.
  • Right-click on the audio device and the JBL headphones, and choose Properties.
  • Now, uncheck the box next to the audio enhancement option in the Enhancement tab.

Reconnect the headphones and try playing sound through your JBL Quantum 100 headphones. If you still don’t hear anything, try the next fix.

Change Your Audio Output Device:

If you have multiple audio devices connected to your system, your system might find it hard to produce sound output through the JBL headphones. So you must ensure that the JBL Quantum 100 headphones are selected as the default choice for sound output.

  • Open up the Control Panel and choose the option Sound.
  • Here, click on the Playback tab.
  • Now select the JBL headphone as the default audio source.
  • Then click on Set Default.

If you still don’t hear anything, try the next fix.

Check For Dirt and Debris:

The JBL Quantum 100 headphones connect to a system with a 3.5mm jack. There is a slight possibility that some dirt or debris is stuck in the port, and despite your attempts to play some audio, the residue is working as a barrier, not letting you get a proper connection. So check the port properly and clean it up as much as possible.

Update the drivers:

Audio drivers need to be updated on Windows systems from time to time. You will need the latest audio drivers on your computer to keep the JBL Quantum 100 headphones running without problems.

There are three ways to update or install audio drivers on a Windows computer. Firstly, you can visit your computer manufacturer’s website, and on their support or download page, you will find the setup file for the audio drivers. You need to download the setup file from that site and then install the drivers onto your computer, just like any other program.

Secondly, you can let Windows look for the drivers and automatically install them on your computer.

  • Double-click on audio inputs and outputs and then right-click on “Microphone.”
  • Select Update Driver.
  • Then follow the on-screen instructions to let your computer scan the internet for the latest drivers.
  • If it finds any new drivers, Windows will automatically install them on your computer.

The last method for updating drivers is to use a third-party driver utility tool. Several tools can scan your computer for any missing or outdated drivers. If the audio driver on your computer is out of date, it will show up in one of these tools. Then you need to click one button, and the latest drivers will be installed on your computer. These driver utility tools charge a bit for their service, but it is well worth it since you do not need to worry about any drivers on your computer again.

If updating the drivers also does not solve your issue, try the next solution.

Reset Windows

Resetting Windows will set everything in Windows to its default setup. You won’t lose any data, but your setting change will be reverted to its default value. This could fix your problem with the headphones.

Uninstall third-party audio tools:

Many of us use third-party equalizer audio tools on our computers to enhance the audio experience. We default get different audio settings and profiles when installing audio drivers. But some users like to tweak their audio experience, and in search of that, they use specific third-party audio tools per their needs. These third-party audio tools could be the cause behind your problem, though.

The JBL Quantum 100 headphones might not be compatible with the third-party audio tool you are using on your computer. In that case, they won’t work correctly no matter what you try with the application installed on your computer. The only solution is to uninstall that third-party audio from your computer entirely.

Run Audio troubleshooter:

Windows has a troubleshooter utility tool built into the OS that can scan the computer for any known issues and try to fix them for the user. If the troubleshooter can’t fix the problem, it will at least display information to the user about what is wrong with the Windows system. So for the sound issue with the JBL Quantum 100, you can also try this.

  • Press Windows Key + I and then select Update & Security from the list of options.
  • Then click on the Troubleshooting tab in the left pane.
  • Click on Additional troubleshooters.
  • Click on the Audio or Speech or any similar audio-related option in the following menu. That will initiate the audio troubleshooting for you. Ensure you have the headphones connected when you are doing this.
  • Let the troubleshooter run the scan and try the fixes for the problems that show up.

After the troubleshooter fixes your problem, you should be able to use the headphones usually.

Contact Support:
