Why is My Audio Not Working on After Effects - GOM Audio
Audio playback problems in After Effects usually stem from codec mismatches, disabled audio output, or corrupted cache files — but the fix depends on what's actually broken. Before you blame the software, here's the real diagnostic path: check if audio is enabled in the timeline, verify your system's audio driver is up to date, and confirm the project file uses supported formats. If AE's audio layer sits silent, the issue likely isn't After Effects itself but how it's configured or what format you're feeding it.
Common Causes: Why Is My Audio Not Working on After Effects
Audio Output Is Muted or Disabled
The most common trap: audio preview is switched off. In After Effects, look at the top right of the timeline panel — that speaker icon needs to be active (not crossed out). If it's muted, click it. Also check the RAM Preview button hasn't been set to "Skip Audio" in the preview panel. This catches people constantly because AE doesn't scream at you when audio is disabled; it just silently plays video.
Codec or Format Incompatibility
After Effects imports audio fine from WAV, AIFF, and MP3, but some compressed formats cause stuttering or complete silence. If you're working with an unusual codec or a file that plays fine in your lightweight audio software, try converting the source to WAV first using a free audio player with conversion tools. Formats matter more than people think — a file that plays in Windows Media Player might choke in AE's timeline.
Cache or Preference Corruption
Rebuild your Audio Hardware preferences. Go to Edit → Preferences → Audio Hardware, then click the "Refresh" button. This forces AE to re-detect your sound card and drivers. If that doesn't work, delete the preferences file entirely (AE creates a fresh one on restart). The file location varies by OS, but it's in your user Application Data folder under Adobe → After Effects.
System-Level Fixes
Update Your Audio Drivers
Windows audio drivers go stale. Download the latest chipset audio drivers from your motherboard or laptop manufacturer's support page, not Windows Update. Realtek, Intel, and NVIDIA drivers especially matter here. Restart after installation.
Check Project Settings
Open Composition → Composition Settings and verify the audio sample rate matches your system (usually 48 kHz for video work, 44.1 kHz for music). Mismatches create silence or crackling. Also confirm audio output is set to "Stereo" or your actual speaker configuration, not "None."
When It's Not After Effects
If you've ruled out AE settings, your system itself might not be playing audio correctly. Test by opening any Windows music player — does basic playback work? Try GOM Audio as a lightweight test player to isolate the problem. If audio works in a free audio player but not After Effects, the issue is definitely project-specific, not system-wide.
Quick Reference Table
| Issue | Solution |
|---|---|
| Speaker icon muted | Click speaker icon in timeline |
| Audio formats unsupported | Convert to WAV before importing |
| No sound on preview | Check RAM Preview isn't set to "Skip Audio" |
| Crackling or stuttering | Update audio drivers from manufacturer |
| Silent in AE but works elsewhere | Rebuild Audio Hardware preferences |
Compare this to foobar2000, which handles audio formats more flexibly — but that won't solve After Effects' specific rendering pipeline issues.
Summing Up
Why is my audio not working on after effects usually boils down to three things: AE settings (mute, preview mode, composition settings), system drivers, or codec incompatibility. Start with the speaker icon, move to preferences, then check your audio drivers. Most issues vanish after those three steps. If silence persists, you're likely dealing with a corrupted project file — salvage it by importing assets into a fresh project.
