Legion Pro 5 Gen 9 AMD Game Audio Stuttering Fix
Audio stuttering during gaming on the Lenovo Legion Pro 5 Gen 9 AMD (Ryzen 7 8845HS) is usually caused by DPC latency spikes — small delays where the CPU handles hardware interrupts too slowly, causing the audio buffer to skip. The fixes below address all common causes.
Update the Realtek audio driver Most common
Go to Lenovo Support, find Legion Pro 5 Gen 9, and download the latest Realtek HD Audio driver. Install it and restart. Outdated audio drivers are the most frequent cause of stuttering that appears specifically during gaming when the GPU and CPU are at high load.
Set audio format to 16-bit, 48000 Hz
Right-click the speaker icon, open Sound settings → More sound settings → Playback. Right-click your audio output, choose Properties → Advanced. Set the format to 16 bit, 48000 Hz. High-resolution formats (192kHz) increase CPU overhead and can cause stuttering during intensive gaming.
Disable audio enhancements
In the same Properties → Advanced dialog, check Disable all sound effects on the Enhancements tab. Spatial sound, bass boost, and equalization effects add processing overhead that can contribute to audio buffer underruns during GPU-intensive scenes in games.
Use Lenovo Vantage to switch to Performance mode
Open Lenovo Vantage and set the performance mode to Performance or Extreme Performance. In Balanced mode, the CPU can step down clock speeds during sudden demand spikes from the audio subsystem, which causes brief audio gaps when the CPU ramps back up.
Update BIOS and chipset driver
Run Lenovo System Update and install the latest BIOS and AMD chipset driver for the Legion Pro 5 Gen 9. AMD chipset updates often include improvements to interrupt routing on the Ryzen 8000 series that directly reduce DPC latency spikes — the root cause of most game audio stuttering.
Common questions
What is DPC latency and how does it cause audio stutter?
DPC (Deferred Procedure Call) latency delays hardware interrupt handling, starving the audio buffer and causing clicks or skips.
How do I check DPC latency on my Legion Pro 5?
Download LatencyMon (free tool). Run it while gaming to identify which driver is causing latency spikes.
Does using USB audio help avoid stuttering?
Sometimes. USB DACs bypass the Realtek driver entirely and can eliminate stuttering caused by Realtek-specific DPC issues.
Does Bluetooth audio stutter more than wired on this laptop?
Yes. Bluetooth audio has higher latency and is more susceptible to DPC interference. Use wired or USB audio for gaming.
Razif, Melaka: “Game audio on my Legion Pro 5 AMD stuttered badly during GPU-heavy scenes. Setting audio to 16-bit 48kHz, disabling enhancements, and updating the AMD chipset driver via Lenovo System Update fixed the stuttering permanently.”
Frequently Asked Questions
Why does game audio stutter only during intense GPU scenes on the Legion Pro 5?
When the GPU is at maximum load, DPC interrupt handling is delayed as the CPU prioritizes GPU work. This starves the audio buffer and causes skips. Switching to Performance mode in Lenovo Vantage and updating the AMD chipset driver reduces this interrupt delay significantly.
Does disabling Game Mode in Windows help with audio stutter?
Sometimes. Windows Game Mode prioritizes CPU resources for the game process, which can inadvertently de-prioritize audio processing. Try disabling Game Mode in Settings → Gaming → Game Mode and see if audio stuttering improves.
Can antivirus software cause game audio stuttering?
Yes. Real-time scanning during gaming generates DPC spikes as the antivirus intercepts file I/O from the game. Add your game installation folder and launcher to the antivirus exclusion list to reduce this impact while gaming.
What is the best audio output format for gaming on the Legion Pro 5?
For headsets and speakers, 16-bit 48000 Hz provides the best balance of quality and CPU overhead. For high-end DACs, 24-bit 96000 Hz is a reasonable upgrade. Avoid 192000 Hz for gaming as it increases buffer overhead without an audible benefit on most audio hardware.
