Root Causes of Audio Glitches in Suyu
Before we look into solutions, it’s crucial to understand why audio issues occur in the Suyu emulator. Unlike native PC games that are designed specifically for your hardware, emulators must translate instructions from one system (Nintendo Switch) to another (your PC) in real-time.
- Performance Bottlenecks represent the most common culprit. Emulation is extraordinarily CPU-intensive, requiring your processor to handle not just the game’s original code but also the translation layer.
- Incorrect Audio Configuration often stems from Suyu’s default settings not aligning with your specific hardware setup.
- Shader Compilation Issues create temporary but noticeable audio disruptions. When Suyu encounters new visual effects or areas it hasn’t processed before, it must compile shaders on the fly.
- Driver Compatibility Problems like outdated graphics drivers, audio drivers, or even Windows updates can introduce compatibility issues that manifest as audio glitches, crackling, or complete sound loss.
Complete Step-by-Step Audio Troubleshooting Guide
There can be multiple reasons for gitchy audio in Suyu. From system updates, graphic cards to Suyu’s settings, let us take a look at the resolving steps.

- Verify that the Output Device matches your primary audio output (speakers or headphones).

- Disable “Enable audio stretching” as this feature can introduce artificial delays and distortions.
- Set the Volume to 100% to ensure maximum dynamic range.

- Click OK and completely restart Suyu to apply the changes.

Step 2: Optimize System Performance for Emulation
Emulation performance directly impacts audio quality. Even minor performance hiccups can cause noticeable audio stutters. Let’s check some setting changes in your system.
Resource Management:
- Open Task Manager (Ctrl + Shift + Esc) and navigate to the Processes tab.

- Close resource-heavy applications like web browsers with multiple tabs, streaming software, or other games.
- End unnecessary background processes, particularly those consuming significant CPU or memory.
Process Priority Adjustment:
- Launch your game in Suyu first.
- In Task Manager, switch to the Details tab.

- Locate suyu.exe in the process list.
- Right-click and select Set priority > High. This instructs Windows to prioritize Suyu’s resource allocation.

- Now, click on the Change priority button.

- Warning: Never set priority to “Real-time” as this can cause system instability.
Windows Power Settings:
- Open Control Panel > Power Options.

- Select High Performance or Ultimate Performance mode.

- Click Change plan settings > Change advanced power settings.

- Expand Processor power management.

- Now, set both minimum and maximum processor state to 100%.

Step 3: Update and Optimize Drivers
Driver issues are responsible for a significant percentage of emulation problems. Keeping drivers current ensures optimal compatibility and performance.
Graphics Drivers:
- NVIDIA Users: Download GeForce Experience and enable automatic driver updates, or manually download the latest Game Ready drivers from NVIDIA’s website.
- AMD Users: Use AMD Software: Adrenalin Edition for automatic updates, ensuring you get both graphics and audio driver updates.
- Intel Users: Download the Intel Driver & Support Assistant for automated driver management.
For Audio Drivers:
- Open Device Manager (Windows + X, then M) or search for it in the search option.
- Click on the > icon beside it to see Sound, video, and game controllers.

- Right-click your audio device option.

- Next, select Update driver software, and then choose the option, Search automatically for drivers.

Windows Updates:
Ensure Windows is fully updated, as Microsoft frequently releases performance improvements and compatibility fixes that can resolve emulation issues.
Step 4: Advanced Graphics Configuration
Graphics performance directly correlates with audio stability in emulation. Optimizing these settings can eliminate audio stuttering.
API Selection:
- In Suyu, navigate to Emulation > Configure.

- Now choose the Graphics option from the right menu.

- Test both OpenGL and Vulkan APIs:

- Vulkan generally provides better performance on modern AMD graphics cards and newer NVIDIA cards.
- OpenGL may offer better stability on older hardware or specific driver versions.
- Enable V-Sync to synchronize frame rendering with your monitor’s refresh rate, reducing both visual tearing and audio desynchronization.

Resolution and Quality Settings:
- Start with 1x resolution scaling to minimize performance impact.

- Gradually increase resolution only if your system maintains stable performance.
- Enable GPU decoding if available for your graphics card.

FAQs
1. Why does audio stutter only when entering new areas or during cutscenes?
This is typically caused by shader compilation. When Suyu encounters new visual effects or environments, it must compile shaders in real-time, temporarily consuming significant CPU resources. The stuttering should disappear once shaders are compiled and cached.
2. Can insufficient RAM cause audio problems in Suyu?
Absolutely. Emulation is memory-intensive, and insufficient RAM forces your system to use slower virtual memory (page file) stored on your hard drive. This creates performance bottlenecks that manifest as both audio and video stuttering. 16GB is recommended for optimal performance.
3. Does the graphics API choice really affect audio quality?
Yes, indirectly but significantly. The graphics API affects overall system performance and resource allocation. If Vulkan provides 20% better frame rates than OpenGL on your system, you’ll experience smoother audio playback because your CPU has more resources for audio processing.
