1. Try G435 on a different device

When your G435 has no sound all of a sudden, the first thing to do is to see if the problem is with the headset itself, or with your computer settings. And the easiest way to do so is to use the headset on a different device.

For instance, when you notice that your G435 doesn’t make any sound when on your computer, try to disconnect it from your current device, and try it on your phone, or another computer via Bluetooth or Lightspeed connection, and see if G435 works fine on a second device.

If the same problem is seen on the second device, the problem could be with the headset itself. In that case, it’s always suggested to try it on a third device. If the Logitech G435 gaming headset doesn’t work either on 3 consecutive devices (computers, tablets, and/or mobile phones), it’s very likely that your headset is at fault. If so, you should talk to Logitech support to see if they can provide further support.

If your Logitech G435 works fine on the other devices but your computer, please move on to the fixes below.

2. Switch between Bluetooth and Lightspeed mode

By switching between the Bluetooth connection mode and the Lightspeed mode, you can reset both connections and see if doing so will fix the G435 headset no sound issue.

To do so:

1. Press the Mute button for 3 seconds or longer.
   
2. Switch to LIGHTSPEED — the LED will light cyan for 5 seconds.
   
3. Switch to Bluetooth, the LED will light blue for five seconds.
   

See if G435 works fine under both modes. If the headset has no sound in either mode, please move on to the next fix.

3. Remove and pair the G435 headset via Bluetooth again

If your Logitech G435 headset still refuses to work at this stage, you can try to reconnect it to your computer.

If you’re connecting the headset to your device via Lightspeed, just unplug the receiver from the USB port and then plug it back in.

If your Logitech G435 headset is connected to your computer via Bluetooth, you should remove the headset first before you connect it again. To do so:

1. On your keyboard, press the Windows key and the I key at the same time to open Settings. Select Bluetooth & devices > Devices.
   
2. Click the three-dot button for your Logitech G435 headset, and select Remove device.
   
3. Click Add device > Bluetooth, and wait for your computer to find your G435 headset again.
   

If your G435 headset still doesn’t have sound after this change, please try the next fix below.

4. Update Windows

If your Logitech G435 headset suddenly has no sound, it’s possible that Microsoft has improved its way of handling Bluetooth devices. To see if this is the culprit, you can update your system to the latest version. To do so:

1. On your keyboard, hit the Windows key, then type check for updates, then click Check for updates.
   
   
2. Click Check for updates, and Windows will scan for any available updates.
   
3. If there are available updates, Windows will automatically download them for you. Restart your computer for the update to take effect if needed.
4. If there are no available updates, you’ll see You’re up to date like this.

Then try your G435 headset again to see if it works. If the problem remains, please move on to the next fix.

5. Select G435 as the sound device in Windows Settings

You can also make sure that the Logitech G435 headset is selected as the output device in the sound setting panel. To do so:

1. On your keyboard, press the Windows key and the I key at the same time to open Settings. Select System > Sound.
   
2. Under the Output panel, select your Logitech G435 headset, and set it as the default output device.

Then see if there’s sound coming out from your G435. If the headset still doesn’t have any sound, please move on.

6. Update the Bluetooth and sound card drivers

Outdated or incorrect sound card and Bluetooth adapter drivers could also be the culprit to the Logitech G435 having no sound problem, so if the above methods don’t help to bring back the sound, it’s likely that you have corrupted or outdated sound and Bluetooth drivers. So you should update your drivers to see if it helps.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to be troubled by the wrong driver you would be downloading, and you don’t need to worry about making a mistake when installing. Driver Easy handles it all.

2. Double-click to expand the Bluetooth category, then right-click your Bluetooth adapter (it’s usually the one without any Microsoft wording) and select Properties.
   
3. Select Power Management, then untick the box for Allow the computer to turn off this device to save power. Then click OK.

9. Repair system files

If you are facing persistent issues with your Logitech G435 gaming headset and none of the previous solutions have proven effective, it’s possible that your corrupted system files are to blame. To rectify this, repairing the system files becomes crucial. The System File Checker (SFC) tool can assist you in this process. By executing the “sfc /scannow” command, you can initiate a scan that identifies problems and repairs missing or corrupted system files. However, it is important to note that the SFC tool primarily focuses on scanning major files and may overlook minor issues.

In situations where the SFC tool falls short, a more powerful and specialized Windows repair tool is recommended. Fortect is an automated Windows repair tool that excels in identifying problematic files and replacing malfunctioning ones. By scanning your PC comprehensively, Fortect can provide a more comprehensive and effective solution for repairing your Windows system.
