If you have a subwoofer or sound system then you have probably heard of port chuffing. Port chuffing is a mild or heavy turbulence of the air in the port. This can be annoying if you use your sound system to listen to music or watch videos and can result in a temporary loss of bass. But don’t worry, this article will show you a few tips on how to stop port chuffing issues with your speaker.
The first thing to try is to change the power outlet. Some outlets are better than others at providing a steady supply of power. If you’re using a laptop, try plugging it into another outlet in your room or house.
You can also try turning off unneeded devices. Make sure there aren’t other devices drawing power from the same outlet as your computer, especially if they’re also plugged into surge protectors or UPSes that provide backup power in case of a brownout or blackout. This can reduce the voltage available for your computer’s needs and cause audio port chuffing. Unplug unused devices until the problem goes away, then plug them back in one at a time to see which one was causing the problem.
Update your BIOS firmware if possible. If your motherboard has an option for updating its BIOS, try doing so, newer versions may include fixes that solve this problem without requiring further troubleshooting on your part.

How to Stop Port Chuffing?
1. Identify the problem
To start, you will need to identify the problem. Chuffing occurs when a speaker is plugged into an audio port that isn’t strong enough to handle the electrical current needed to produce its sound. This means it’s possible for your device to chuff even if you have it plugged into a working power source, as long as there are other factors interfering with the flow of electricity through the port.
Often, chuffing can be caused by faulty or damaged hardware on your device, but just because one piece of hardware is causing problems doesn’t mean they’re all bad. If you’re having issues with your phone’s speakers or mic input, try swapping out damaged parts for new ones, it might do wonders for your experience.
2. Try reducing the mic sensitivity
There’s a good chance that the problem is the microphone sensitivity setting. You can change this in your settings menu under the “Voice” or “Mic” tab, depending on what phone you have.
In order to find out how much you’re currently lowering your mic sensitivity setting, open up an audio recording app (like Audacity) and record yourself talking normally into your phone’s microphone. Playback this recording and write down how loud it sounds at 1 meter away from where you recorded it. Then, make sure the voice call volume on your phone is turned all the way up, then re-record yourself into Audacity again while holding it at 1 meter away from where you recorded previously. This time playback both recordings side by side with each other so that they sound similar in volume since we already know one was recorded with full volume and one wasn’t.
3. Clean the microphone and audio port
If you have a device with a microphone and audio port, you should clean them regularly to remove any debris that may be clogging the port. If you notice static or fuzziness while talking on your phone, this could be a sign of buildup in the microphone or audio ports.
To clean these areas:
- Use a soft brush or cotton swab to gently clean out any debris from inside the microphone and audio ports.
- If needed, use alcohol or isopropyl alcohol to disinfect your device’s internal components before inserting them back into the smartphone case or tablet cover. This will help prevent further bacterial growth that could lead to buildup again in the future. Dry off any excess moisture using paper towels.
4. Update your firmware
If you have a device with an audio port, make sure you update the firmware on your device. This step is especially important if you’re using an older model.
The first thing to do is check if there’s a firmware update available for your device. If there is one and you want to update it, follow these steps:
- Download the latest version of AudioPort Update Utility from our website or use the built-in tool in AudioPort Update Utility (if installed).
- Connect the audio output of your computer to an input source and plug in two 3/8″ plugs into AudioPort Update Utility’s inputs
- Select “Firmware Upgrade” under the “Tools” menu option and press Enter key when prompted
5. Check the microphone sensitivity setting
The microphone sensitivity setting is a feature that enables you to adjust the volume of your recording. If this setting is too high, your microphone will pick up more background noise and other sounds. You can check your current microphone sensitivity settings by following these steps:
- Open the Settings app on your iPad.
- Go to General > Accessibility > Hearing & Sound and tap Microphone Sensitivity.
- Slide the slider all the way to the left for less sensitivity or all the way to the right for greater sensitivity.
6. Reset your device to factory settings
Re-install the operating system. If you have a Mac, you can use the Recovery Disk Assistant to re-install macOS. On Windows, visit Apple Support for more information about reinstalling Windows 10. Reset your device to factory settings. This will delete all of your data, so make sure that you back up before proceeding.
You may also need to re-connect your devices after this step has been completed. For example, if they were connected via Wi-Fi before resetting them in which case it’s best not to turn off that connection until after starting over so as not to interrupt any downloads, but since each manufacturer uses different terminology for these steps it’s worth checking with them directly first before proceeding down this path.
7. Try a different audio app
If you’re using an app with a chuffing problem, try switching to another audio app. There are plenty of great options out there; if one doesn’t work for you, try another until you find one that does.
If the sound quality of your calls is poor and the person on the other end can hear it in their voice, it might be because they are using an older phone or running outdated operating systems like Android 4.3 or iOS 8.0+. If so, consider upgrading their device or providing them with an older version of your app so they don’t hear what they would call “tinny” sounds from their end.
8. De-solder and re-solder all pins on the audio port
If you’ve tried the previous steps and chuffing is still happening, you may want to try a more involved method. To do this, you’ll need a soldering iron and some solder. You will also want to unplug the device from power before starting.
I. Remove all pins
First, remove all of the pins from both sides of the audio port with your soldering iron, you can use a heat gun if you don’t have one. Be careful not to touch anything else while removing them as it can cause damage if done incorrectly.
II. Clean residue
Next, clean off any residue with alcohol wipes or cotton swabs until there is no more dust or dirt on either side of the connector or around it. Make sure that both sides are thoroughly cleaned so that any leftover substances don’t cause further problems later on when putting things back together again.
III. Solder pins into place
Now re-solder all eight pins back into place using new ones made specifically for them; these should be available at most electronics stores near where you live; just make sure they’re compatible before buying. They’re usually pretty cheap too which makes them even better value for money.
FAQs On Speaker Port Noise
What causes subwoofer port noise?
Subwoofer port noise, also known as chuffing, is a rustling sound caused by the air breaking apart as it exits the port. This is usually the result of a straight port with no contour at either end. It can also happen if the subwoofer is being driven too hard, causing it to bottom out. This can be due to a bass null location in the room, which is why experts recommend doing a “bass crawl” to find the best location for your subwoofer.
What happens if you block the port of a speaker?
If you block the port of a speaker, it will no longer be ported and will behave like a sealed system. This means that the bass alignment will be different, and the low frequencies will roll out differently. It’s not recommended to block the port unless you have a specific reason to do so, such as reducing the overall size of the speaker.
Does sound come out of a port on a speaker?
Yes, sound does come out of a port on a speaker. The port pushes air out when the woofers move back and sucks air in when the woofers move forward. The direction in which the port fires the sound depends on the location of the port, with rear ports requiring a wall behind them to bounce the sound back toward the listener.
What sounds better ported or sealed?
When it comes to home theater systems, ported subwoofers are generally considered better than sealed ones. This is because they provide maximum dynamic impact and deep bass extension, which is essential for an immersive movie-watching experience. However, sealed subwoofers are better suited for music listening, as they provide tighter, more accurate bass. Ultimately, the choice between ported and sealed subwoofers comes down to personal preference and the specific needs of your setup.
Final Thoughts on Fixing Port Chuffing in Speakers
If your speaker is producing chuffing noises, try steps like reducing the microphone’s sensitivity and cleaning the ports. To clean the port, use a cotton swab to use compressed air to clean the port of debris. If you don’t have cotton swabs or compressed air, use a Q-tip instead.
Try using a different music app, or another audio source. Suppose it’s not your microphone causing chuffing. In that case, something else might be interfering with playback at specific frequencies near 1 kHz like an overpowered air conditioner or fan running nearby that you can’t control or move away from.
