Common PCSX2 Audio Problems Explained
Before applying fixes, it’s important to understand what type of audio problem you are facing. PCSX2 audio issues usually fall into one of the following categories:
Sound Crackling / Distorted Audio
-
Audio breaks, pops, or crackles
-
Sound becomes rough during gameplay
-
Happens more during intense scenes
Audio Lag or Delay
-
Sound comes late compared to video
-
Dialogues don’t match character movement
No Sound at All
-
Game runs but audio is completely silent
-
Happens after changing settings or devices
Audio and Video Out of Sync
-
Music plays faster or slower than gameplay
-
Cutscenes feel unnatural
All these issues have specific causes, and each one requires a slightly different fix.
Why Audio Problems Occur in PCSX2
PCSX2 does not simply “play sound” like a normal game. It emulates the PlayStation 2 sound hardware, which is heavily dependent on timing and CPU performance.
Let’s break down the main causes.
Low FPS Causes Audio Issues
This is the number one reason for audio crackling and stuttering.
Important rule:
If FPS drops, audio will break.
PCSX2 tries to keep audio and video synchronized. When your PC cannot maintain full speed:
-
Audio buffers run out
-
Crackling and popping start
-
Sound may stretch or distort
Fixing FPS issues often automatically fixes audio problems.
Wrong Audio Plugin Settings
PCSX2 uses an audio plugin called SPU2-X.
Wrong settings in this plugin can cause:
-
Sound distortion
-
Audio delay
-
No audio output
CPU Overload
PCSX2 is CPU-heavy. When the CPU is overloaded:
-
Audio processing gets delayed
-
Buffers fail to refill in time
This is common on low-end or older CPUs.
Outdated PCSX2 Version
Older PCSX2 builds had:
-
Audio bugs
-
Poor synchronization
-
Less optimization
Using an outdated version can cause unnecessary audio problems.
PCSX2 Audio Fix – Basic Checks (Do These First)
Before changing advanced settings, do these basic checks:
-
Restart PCSX2
-
Restart your PC
-
Check Windows volume mixer
-
Make sure correct audio output device is selected
-
Ensure BIOS is correctly detected
Sometimes, audio issues are caused by simple device mismatches.

Best PCSX2 Audio Settings (Recommended)
This section is the core of PCSX2 Audio Fix.
Recommended Audio Plugin
-
SPU2-X (default and best)
Output Module (Very Important)
Best options:
-
XAudio2 (recommended for most users)
-
DirectSound (use only if XAudio2 fails)
XAudio2 offers:
-
Better performance
-
Lower latency
-
Cleaner sound
Synchronization Mode
Recommended:
-
TimeStretch
This mode adjusts audio speed smoothly when FPS fluctuates, preventing crackling.
Avoid:
-
Async Mix (can cause desync)
-
No sync (unstable)
Audio Latency / Buffer Size
-
Default buffer is usually fine
-
If crackling occurs → increase buffer slightly
Do NOT set buffer too low.
Lower buffer = lower latency but more crackling.
PCSX2 Audio Crackling Fix (Step-by-Step)
Audio crackling is the most common problem.
Step 1: Fix FPS First
-
Lower internal resolution
-
Disable heavy graphics enhancements
-
Use correct renderer
If FPS stabilizes, audio crackling often disappears automatically.
Step 2: Increase Audio Buffer
-
Go to SPU2-X settings
-
Increase latency slightly
-
Test again
Step 3: Enable TimeStretch
-
Turn ON TimeStretch
-
Adjust sync sensitivity if needed
Step 4: Reduce CPU Load
-
Close background apps
-
Disable unnecessary overlays
-
Set Windows power plan to High Performance
PCSX2 Audio Delay Fix (Sound Comes Late)
Audio delay usually means audio and video are not synchronized properly.
Fix Audio Delay:
-
Use TimeStretch sync
-
Avoid very high buffer values
-
Ensure FPS is close to 100%
Too much buffering can cause delay, so balance is important.

Recommended Windows Tweaks:
-
Set sample rate to 44100 Hz or 48000 Hz
