How to Fix Glitch Sounds on PC, TV, and Streaming Devices

Glitch sounds refer to abnormal audio behavior such as crackling, popping, skipping, stuttering, or robotic-sounding playback. Many users notice audio glitching on Windows PCs during gaming or streaming, on smart TVs while watching content on platforms like Netflix or YouTube, or when using HDMI-connected devices such as streaming boxes and consoles. In some cases, glitch sounds only happen when playing specific downloaded files, which often indicates file corruption rather than a system issue.

This guide will help you identify where the glitch sounds are coming from and apply the correct fix based on the actual cause, whether it’s a configuration issue, hardware problem, or file-level corruption.

Part 1. What Are Glitch Sounds and Why Do They Happen?

Glitch sounds happen when audio data is not processed or delivered properly from the source to the output device. This disruption can occur at different stages, including decoding, processing, or playback.

Below are the most common technical causes explained in practical terms:

• Buffer underruns - Audio systems process sound in small chunks called buffers. If your system cannot process the audio fast enough due to high CPU usage or driver latency, gaps occur, which you hear as pops, clicks, or stutters.
• Sample rate mismatches - Audio systems process sound in small chunks called buffers. If your system cannot process the audio fast enough due to high CPU usage or driver latency, gaps occur, which you hear as pops, clicks, or stutters.
• Driver latency or driver faults - Outdated or corrupted audio drivers can delay communication between the operating system and audio hardware, resulting in inconsistent playback.
• HDMI signal interference - HDMI carries both audio and video digitally. Poor-quality cables, loose connections, or interference can interrupt the signal, causing sound glitches.
• Corrupted audio files - If an audio file becomes damaged during download, transfer, or storage, parts of the sound data may be missing or unreadable, which results in glitch sounds during playback.

It is important to distinguish between:

• System-wide glitch sounds — affect everything you play
• File-specific glitch sounds — affect only certain media files

This distinction determines the correct solution.

Part 2. Identify Where the Audio Glitching Is Coming From

You need to identify the source of the problem before applying fixes. This prevents unnecessary troubleshooting and helps you choose the right solution faster.

Step 1: Test Different Audio Sources

Play audio from multiple apps and files to compare behavior.

For example:

• Play a YouTube video
• Play a local music file
• Play audio from another app

If glitch sounds happen everywhere, the issue is likely system-related. If it happens only in one file, the file itself may be corrupted.

Step 2: Test Different Output Devices

Switch between different playback devices to isolate the problem.

For example:

• Try headphones instead of speakers
• Try external speakers instead of built-in speakers
• Change HDMI ports or cables

If the glitch disappears on another device, the original hardware may be faulty.

Step 3: Observe the Pattern

Pay attention to patterns, such as:

• Only during gaming → system resource issue
• Only on TV apps → TV firmware issue
• Only specific files → file corruption

Once you identify the pattern, apply the relevant fixes below.

Part 3. How to Fix Glitch Sounds on Windows PC

Fix 1. Restart Windows Audio Services

Audio services manage sound processing in the background. Restarting them refreshes the audio system and resolves temporary glitches.

Step 1. Press Windows + R, type services.msc, and press Enter or click OK.

Step 2. Find Windows Audio, right-click it, and select Restart. Restart your computer and test the audio again.

Fix 2. Update or Reinstall Audio Drivers

Drivers act as the communication bridge between your system and sound hardware. Corrupted or outdated drivers are one of the most common causes of glitch sounds.

Step 1. Right-click Start and open Device Manager. Expand Sound, video and game controllers.

Step 2. Right-click your audio device and select Update driver. Restart your computer after updating.

Fix 3. Adjust Audio Format Settings

Incorrect audio format settings can create compatibility problems.

Step 1. Go to Settings. Scroll down and select Sound. Choose your output device.

Step 2. Under Properties, change the format to 44,000 Hz or 48,000 Hz. Apply changes and test audio.

Fix 4. Disable Audio Enhancements

Enhancement features sometimes conflict with hardware.

Step 1. Open Sound settings. Select your output device.

Step 2. Under Properties, Disable audio enhancements. Restart and test.

Fix 5. Reduce System Load

High CPU usage interrupts audio processing.

Close:

• Games running in the background
• Editing software
• Multiple browser tabs

Part 4. How to Fix TV Glitching Sound Issues

TV glitch sounds are usually caused by firmware bugs, cable problems, or incorrect settings.

Fix 1. Power Cycle the TV

Power cycling resets the TV’s internal processes and clears temporary bugs that may interfere with audio playback. This is often effective if the glitch started suddenly without any changes to your setup.

Step 1. Turn off the TV and unplug it from the power outlet.

Step 2. Wait 60 seconds, then plug it back in and turn it on to test the sound.

⚠️ Risk Note: This process is safe and will not delete your settings, but avoid repeatedly unplugging the TV quickly, as sudden power interruptions may stress the hardware over time.

Fix 2. Check HDMI and External Devices

HDMI cables and external devices like streaming boxes, soundbars, or consoles are common sources of audio glitches if the connection becomes loose or unstable. Even minor cable wear can disrupt the digital audio signal.

Step 1. Disconnect the HDMI cable from both the TV and the connected device.

Step 2. Reconnect it securely, or try a different HDMI cable or port if the issue continues.

⚠️ Risk Note: Avoid forcing HDMI cables into the port, as this can damage the connector pins and lead to permanent connection problems.

Fix 3. Update TV Firmware

TV firmware controls how the system handles audio and video processing, and outdated versions may contain bugs that cause glitch sounds. Installing the latest update ensures compatibility with apps and external devices.

Step 1. Open Settings and select System.

Step 2. Scroll down and choose Software Update, then install any available updates.

⚠️ Risk Note: Do not turn off the TV during the update process, as interrupting a firmware update can cause system errors or startup issues.

Fix 4. Reset TV Audio Settings

Incorrect audio settings, especially after updates or when connecting external devices, can cause compatibility issues that result in glitching sounds. Resetting the audio settings restores the default configuration and removes any conflicting adjustments.

Step 1. Open Settings on your TV and go to Sound or Audio Settings.

Step 2. Select Reset Audio Settings or Restore Default Sound Settings, then confirm and test the audio.

⚠️ Risk Note: This will remove custom sound presets, equalizer adjustments, and sound output preferences, so you may need to reconfigure them afterward.

Fix 5. Perform a Factory Reset (Last Resort)

If glitch sounds persist after trying all other fixes, performing a factory reset can resolve deeper system or firmware issues. This process reinstalls the TV’s original system state and removes corrupted settings that may be affecting audio performance.

Step 1. Go to Settings, then select System or General, and choose Reset or Factory Reset.

Step 2. Confirm the reset and allow the TV to restart, then set it up again and test the sound.

⚠️ Risk Note: A factory reset will erase all installed apps, accounts, and personal settings, so make sure you remember your login information before proceeding.

Part 5. If Sound Glitching Happens Only in Certain Files (Optional)

If glitch sounds occur only in specific audio files, the problem is likely file corruption rather than device or system configuration. This commonly happens after interrupted downloads, unsafe USB removal, recording errors, or transfer failures.
