Lenovo ThinkPad E16 Gen 2 AMD Ryzen 7 7735HS Audio Crackling Fix Windows 11

The speakers or headphone output on your Lenovo ThinkPad E16 Gen 2 AMD Ryzen 7 7735HS produces crackling, popping, or distortion during audio playback. Realtek audio driver updates and audio enhancement settings resolve crackling on the ThinkPad E16 Gen 2 AMD.

This guide covers Realtek audio driver updates, Windows audio enhancement settings, and sample rate configuration to fix audio crackling on the Lenovo ThinkPad E16 Gen 2 AMD Ryzen 7 7735HS in Windows 11.

“ThinkPad E16 Gen 2 AMD speakers crackled during video calls. Lenovo Vantage had a Realtek audio driver update. After installing and disabling audio enhancements, crackling completely stopped.” – Amir Hamzah, project manager from Subang Jaya

Why Audio Crackles on Lenovo ThinkPad E16 Gen 2 AMD

The Realtek audio driver on the ThinkPad E16 Gen 2 AMD manages sample rate conversion between application audio output and the hardware DAC. When Windows audio enhancements apply additional processing (EQ, bass boost, or spatial sound) on top of the Realtek driver, the combined processing chain can introduce latency glitches that manifest as crackling. AMD platform power management can also cause the Realtek controller to enter power-saving states during audio playback, creating brief audio dropouts that sound like clicks or pops.

• Realtek audio driver version with known crackling bug on AMD Ryzen 7 7735HS platform
• Windows audio enhancements applying processing that conflicts with Realtek output path
• Audio sample rate mismatch between application (44100Hz) and Realtek driver (48000Hz)
• Realtek HD Audio controller entering AMD power-saving state during playback pauses

Fix 1 – Update Realtek Audio Driver via Lenovo Vantage

Open Lenovo Vantage and go to System Update. Install Realtek High Definition Audio driver update. Restart. Updated Realtek drivers for the ThinkPad E16 Gen 2 AMD include fixes for specific crackling scenarios on the AMD Ryzen 7 7735HS platform audio path. After driver update, play audio immediately to check if crackling is resolved before making additional changes – some users find the driver update alone resolves all crackling without needing enhancement or sample rate changes.

Fix 2 – Disable Windows Audio Enhancements

Right-click the speaker icon in taskbar and select Sound settings. Click the arrow next to the active speaker or headphone output. Scroll to Additional device properties – Enhancements tab. Check Disable all enhancements. Click OK. Also go to the Advanced tab and uncheck Enable audio enhancements under Exclusive Mode. Windows audio enhancements like bass boost, virtual surround, and room correction apply real-time DSP that can overload the Realtek processing pipeline on the ThinkPad E16 Gen 2 AMD during simultaneous multi-application audio playback.

Set Correct Sample Rate

In the same Advanced tab of speaker properties, set Default Format to 24 bit, 48000 Hz (Studio Quality). Applications that output at 44100Hz (most music) require Windows to resample to 48000Hz for the Realtek DAC. The Windows audio engine handles this resampling, but a mismatch between the engine sample rate and the Realtek hardware can cause crackling during the resampling process. Setting 48000Hz as the fixed rate and allowing Windows to resample incoming audio cleanly reduces crackling from sample rate mismatch.

Fix 3 – Disable Realtek Audio Device Power Saving

Open Device Manager and expand Sound, video and game controllers. Right-click Realtek High Definition Audio – Properties – Power Management. Uncheck Allow the computer to turn off this device to save power. On the AMD Ryzen 7 7735HS platform, the Realtek audio controller can enter a low-power state between audio events. When new audio starts playing, the controller takes 50-200ms to wake from power saving – during this transition, the first audio samples are dropped or garbled, producing a click or pop at the start of audio playback.

Fix 4 – Reinstall Dolby Audio App

If Dolby Audio or Dolby Atmos is installed on the ThinkPad E16 Gen 2 AMD, open Microsoft Store and update Dolby Access. If crackling started after a Dolby app update, uninstall Dolby Access from Settings – Apps and test audio without Dolby processing. Reinstall Dolby Access after the Realtek driver update from Lenovo Vantage – installing in this order ensures the Dolby APO registers correctly with the updated Realtek driver version rather than the previous incompatible driver that may have caused the crackling.

Frequently Asked Questions

Why is audio crackling on Lenovo ThinkPad E16 Gen 2 AMD?

Realtek driver bug, Windows audio enhancements conflict, or power saving state. Update Realtek driver via Lenovo Vantage and disable audio enhancements in Sound properties.

How do I fix audio crackling on Lenovo ThinkPad E16 Gen 2?

Lenovo Vantage Realtek driver update, disable audio enhancements, set 48000Hz sample rate, disable Realtek power saving in Device Manager.

Does Lenovo ThinkPad E16 Gen 2 AMD have Dolby Audio?

Some configurations have Dolby Audio via Realtek APO. Update Dolby Access from Microsoft Store – Dolby app version conflicts with Realtek driver are a known crackling cause.

Why does Lenovo ThinkPad E16 Gen 2 audio crackle on headphones?

Realtek power saving switching between headphone and speaker paths. Disable Allow the computer to turn off this device in Device Manager audio properties.

Conclusion

Lenovo ThinkPad E16 Gen 2 AMD Ryzen 7 7735HS audio crackling in Windows 11 is resolved by updating the Realtek audio driver via Lenovo Vantage and disabling Windows audio enhancements in Sound properties. Setting the sample rate to 24-bit 48000Hz prevents resampling-related crackling. Disabling Realtek controller power saving eliminates click artifacts at audio playback start. Dolby Audio app update from Microsoft Store resolves Dolby APO and Realtek driver version conflicts for clean audio output.
