The Dell XPS 13 9340 speakers or headphones produce crackling or popping sounds during audio playback. The Intel Core Ultra 7 155H uses Realtek HD Audio for speaker output. Buffer management issues and exclusive mode conflicts are the most common causes on this platform.

Fix 1 — Disable Exclusive Mode
- Right-click the speaker icon → Sound settings → More sound settings
- Playback tab → Speakers (Realtek) → Properties → Advanced tab
- Uncheck “Allow applications to take exclusive control of this device”
- Also uncheck “Give exclusive mode applications priority”
- Click OK and test audio

Fix 2 — Set Sample Rate to 24-bit 48000 Hz
Same Speakers Properties → Advanced tab. In the Default Format dropdown, select 24 bit, 48000 Hz (Studio Quality). Click Test — if crackling stops with this rate, the mismatch was the cause.
Fix 3 — Reinstall Realtek Audio Driver
Download the Realtek audio driver from Dell Support for XPS 13 9340. Uninstall in Device Manager → Sound, video and game controllers → Realtek High Definition Audio. Install the Dell version and restart.
Fix 4 — Disable USB Audio Power Saving
If using a USB audio adapter or headset, device Manager → USB audio device → Properties → Power Management → uncheck “Allow the computer to turn off this device to save power.”

Frequently Asked Questions
Why does audio crackle on Dell XPS 13 9340?
The Dell XPS 13 9340 uses a Realtek audio codec paired with the Intel Core Ultra 7 155H. Crackling audio is commonly caused by the Windows audio exclusive mode setting, which can cause buffer underruns when apps compete for the audio device.
How do I fix audio crackling on Dell XPS 13 9340?
Right-click the speaker icon → Sound settings → More sound settings → Playback tab → Speakers → Properties → Advanced tab. Uncheck “Allow applications to take exclusive control of this device.” This prevents buffer conflicts.
Can the sample rate cause crackling on Dell XPS 13 9340?
