Why Does The OnePlus 9RT Speaker Crackle?

Before trying any fixes, it’s good to know what’s causing the problem. Here are the common reasons behind the OnePlus 9RT speaker crackling issue:
Dust or Debris in the Speaker Grille
Tiny dust particles can get trapped in the speaker holes over time. When sound passes through a blocked or dusty speaker, it creates a crackling or muffled effect. If you often keep your phone in your pocket or use it outdoors, dust buildup is likely the main reason.
Moisture or Water Damage
Even small drops of water or high humidity can affect the speaker’s performance. The OnePlus 9RT does not have full water resistance. Moisture exposure can cause crackling, distortion, or even complete speaker failure.
Software or App Glitches
Sometimes, the problem isn’t with the hardware. A recent software update or a third-party app can interfere with your audio output. These glitches can cause temporary sound distortion or affect only specific apps like YouTube or WhatsApp calls.
Faulty Audio Settings or Equalizer
Incorrect sound settings or a poorly configured equaliser can make your audio output uneven. Adjusting or resetting sound settings can sometimes fix the issue without any hardware repair.
Damaged Speaker Component
If your phone has been dropped or exposed to high volume for long periods, the speaker’s internal components may have worn out. Physical damage or overuse can easily lead to speaker crackling or buzzing sounds. This usually needs professional phone repair.

Quick Checks Before Going For Repair

Now that you know the common reasons for OnePlus 9RT speaker crackling, try these quick steps before visiting a service centre:
Restart Your Phone
Restarting helps reset temporary glitches that may cause sound problems. Once restarted, play music or a video to see if the crackling has stopped.
Check Volume and Sound Settings
Lower the volume slightly and check if the distortion reduces. Go to your phone’s sound settings or equaliser and reset them to default. This ensures there are no custom sound settings causing uneven output.
Clean the Speaker Area
Use a soft brush or clean, dry cloth to gently remove any dirt or lint from the speaker grille. Avoid sharp objects or blowing air directly into the speaker, as it could push the dust deeper.
Update Software
Check for pending system updates. Software updates often include fixes for minor audio issues. Keeping your phone updated helps improve stability and performance.
Test with Headphones
Plug in wired or Bluetooth headphones and check if the sound is clear. If the crackling disappears when using them, the speaker is likely the problem. In that case, you may need to fix OnePlus 9RT speaker crackling with a proper repair.
