How to Fix Facebook Video Sound Glitch on Galaxy S24 (One UI 8.5)

I was relaxing on my couch last night, scrolling through my feed on my Samsung Galaxy S24 Ultra, when a video caught my eye. I tapped it, expecting to watch a quick clip, but instead, I was hit with an incredibly annoying, choppy sound interruption. The audio kept cutting out and stuttering every few seconds. At first, I thought my Bluetooth earbuds were acting up, so I disconnected them—but the glitch persisted through the phone's stereo speakers. Strangely, when I hopped over to YouTube and Instagram, the sound was flawless. My device had just updated to One UI 8.5 based on Android 16, and it was clear that a deep system-level audio routing conflict had emerged between the new software and the Facebook app's media player.

This wasn't just a minor annoyance; it completely ruined the experience of using the device. When you invest in a flagship premium tier phone, you expect seamless media playback across every application. If you are experiencing this exact same issue where Facebook videos stutter, crackle, or drop audio while other platforms work perfectly, you do not have to wait weeks for an official patch. Let's look at why this happens and implement the exact engineering workarounds needed to restore pristine sound to your device.

Quick Answer

The Facebook video sound glitch on the Galaxy S24 series running One UI 8.5 (Android 16) is caused by a hardware abstraction layer (HAL) mismatch between Facebook’s internal ExoPlayer engine and Samsung’s updated Dolby Atmos framework. To fix this immediately, navigate to Settings → Sounds and Vibration → Sound Quality and Effects and toggle Dolby Atmos off and back on, or switch the Facebook app's battery configuration to Unrestricted to prevent the OS from throttling its background audio threads. If the stuttering persists, clearing the system cache partition via Recovery Mode or installing the official Facebook Beta client will resolve the underlying code regression.

Why This Matters

Media consumption is one of the core pillars of the smartphone user experience. When a flagship device suffers from systematic audio degradation, it directly impacts user satisfaction, device reliability, and overall productivity.

• Media Engine Stability: The underlying issue signals a deeper system framework optimization challenge where third-party media players fail to properly communicate with Samsung’s multi-channel audio drivers.
• System Resource Management: On Android 16, background processes are managed with extreme stringency. If an app's audio pipeline is flagged or delayed by even a few milliseconds by the OS, it manifests as hardware-level stuttering or crackling.
• Hardware Longevity Perception: While this is strictly a software compatibility issue, continuous audio dropouts can cause users to misinterpret the glitch as a blown speaker or a failing physical audio IC component.

Tracking the Roots: One UI 8.5 Media Codec Mismatch

The rollout of One UI 8.5 based on Android 16 introduced advanced performance architectures, including Knox Enhanced Encrypted Protection (KEEP) and the Personal Data Engine (PDE). However, deep within the system's core audio framework, major changes were made to how media streams are processed. Samsung altered its SoundAlive and spatial audio routing to better integrate with real-time Galaxy AI features like Audio Eraser and live Call Captions.

Because the Facebook app utilizes a highly customized version of the Google ExoPlayer framework rather than the standard Android system media player, it struggles to adapt to these strict dynamic resource policies. When Facebook plays a video, it attempts to force a standard stereo stream. Meanwhile, the Galaxy S24 system firmware tries to upmix or process that stream through its local Dolby Atmos engine. On One UI 8.5, this creates an algorithmic processing loop. The buffer underrun that follows causes the exact "annoying sound interruption" described by users across online tech communities.

Step-by-Step Troubleshooting Framework for Galaxy S24

Since standard troubleshooting methods like clearing the app cache or performing a basic reinstallation do not alter how the system core processes app audio, you must utilize advanced configurations. Follow these technical solutions in sequence to systematically isolate and eliminate the audio glitch.

1. Reconfigure App Performance Limits (Disable Throttling)

Android 16 introduces aggressive application standby buckets. If the OS classifies Facebook's media playback threads as non-essential or trims its power consumption while processing heavy video feeds, the audio synchronization will drop out entirely.

1. Launch the Settings application on your Galaxy device.
2. Scroll down and select Apps.
3. Locate and tap on Facebook from the list of installed applications.
4. Within the App Info screen, tap on Battery.
5. Switch the setting from Optimized to Unrestricted.

By forcing the application into Unrestricted mode, you prevent One UI 8.5 from putting media rendering threads to sleep, ensuring a continuous data stream to the physical audio hardware layer.

 

2. Reset the Dolby Atmos System State

Because the glitch is heavily tied to the hardware abstraction layer handling spatial profiles, cycling the system's Dolby Atmos engine can force the device to re-initialize its connection to active app players.

1. Pull down the notification shade to access the Quick Panel and tap the Settings (gear) icon.
2. Tap on Sounds and vibration.
3. Scroll down to the bottom and select Sound quality and effects.
4. Locate Dolby Atmos. If it is currently turned ON, toggle it OFF.
5. Exit back to your home screen, launch Facebook, and play a video for 10 seconds.
6. Return to the menu (Settings → Sounds and vibration → Sound quality and effects) and toggle Dolby Atmos back ON. Set the profile configuration to Auto or Movie.

3. Clear the Galaxy S24 System Cache Partition

Major Android operating system updates leave legacy compilation files, leftover configuration scripts, and stale system caches within the protected storage blocks of your phone. These old files frequently cause system daemons to misbehave. Clearing the cache partition deletes zero personal data but forces the OS to recompile its global system linkages.

1. Power down your Galaxy S24 completely.
2. Connect your phone to a desktop PC, laptop, or Type-C wired headphones using a high-quality USB-C cable (this step is mandatory on modern One UI builds to trigger recovery mode authorization).
3. Press and hold both the Power Button and the Volume Up Button simultaneously.
4. Release both buttons the exact moment the Samsung logo flashes on screen. Your device will boot into the Android Recovery Menu.
5. Use the Volume Down Button to navigate through the text choices until you highlight Wipe Cache Partition.
6. Press the Power Button once to select this action.
7. Tap the volume button to highlight Yes, then confirm by pressing the Power Button.
8. Once the screen displays "Cache wipe complete" at the bottom left, verify that Reboot system now is highlighted, and press the Power Button one final time.

Troubleshooting Level	Technical Action	Targeted Resolution Component	Risk to User Data
Level 1	Set App Battery to Unrestricted	Prevents Android 16 thread throttling	None (Slightly higher idle drain)
Level 2	Cycle Dolby Atmos Hardware Layer	Resets SoundAlive processing paths	None
Level 3	Wipe System Cache Partition	Purges broken pre-compiled files post-update	None
Level 4	Enroll in App Beta Channel	Pushes new API configurations for Android 16	None

4. Bypass Legacy APIs by Joining the Facebook Beta Program

Because Meta develops patches iteratively, public production releases can lag behind major system updates like One UI 8.5. Enrolling in the official beta pipeline provides access to updated software manifests that natively recognize Android 16's media pipeline rules.

1. Launch the Google Play Store on your phone.
2. Tap into the top search bar, type in Facebook, and open its dedicated store landing page.
3. Scroll down past the developer contact details until you find a section labeled Join the beta.
4. Tap on Join and confirm your choice.
5. Wait roughly 5 to 10 minutes for the servers to register your account profile, then refresh the application page.
6. An option to update to the Facebook Beta variation will appear. Download and install the new software package.

Pro Tip

If you want an advanced way to manage media problems across different apps without changing your overall phone settings, download the official Sound Assistant module from Samsung's official Galaxy Store (part of the Good Lock suite). Once inside Sound Assistant, activate the Separate App Sound feature or assign Individual App Volumes. By explicitly giving Facebook its own dedicated media stream channel separate from the main system framework routing, you completely bypass the One UI 8.5 global Dolby Atmos audio mix loop, permanently solving the stuttering problem.

Frequently Asked Questions

Why does this audio glitch happen only inside the Facebook app?

Unlike applications like YouTube or Instagram, which natively interact with modern Android media APIs, Facebook utilizes a modified media architecture. When One UI 8.5 updated the system's underlying audio routing layer to support advanced Galaxy AI capabilities, it created an optimization conflict exclusive to Facebook’s rendering engine.

Will resetting my app preferences fix the sound interruption?

Resetting app preferences might temporarily restore default values, but it will not permanently fix this problem. The stutter occurs because of how the operating system actively manages audio background processing threads on Android 16, which requires changing the app's battery optimization profile to Unrestricted.

Is my Galaxy S24 speaker damaged if the sound crackles?

No. If the audio distortion, cutting out, or stuttering disappears when you play a high-definition video inside YouTube, your physical hardware components are working perfectly. The crackling or interruption is entirely caused by a software buffer underrun within the app framework.

Does wiping the system cache partition erase my photos or messages?

Not at all. Wiping your phone's cache partition only targets temporary operational files, system execution logs, and post-update installation artifacts. Your personal files, system apps, photos, messages, and accounts remain completely untouched.

How long does it take for Meta to release a fix for One UI updates?

While secondary compatibility updates are deployed frequently, public production fixes can take several weeks to roll out to all regions. Joining the Facebook Beta program through the Google Play Store allows you to skip this waiting period and download the fix immediately.

Should I downgrade my phone back to One UI 8.0 to solve this?

Downgrading your operating system firmware is highly discouraged. It requires completely wiping your phone to factory settings, flashes unstable system blocks, and removes critical new security protections like Knox Enhanced Encrypted Protection (KEEP). Following the setting workarounds detailed above is a much safer solution.
