YouTube playing audio but video is black — fix the silent-screen bug
You hear the audio playing but the video area is black or frozen. The player shows progress, you can hear timestamps tick, but the visual is gone or stuck on one frame.
Why this happens
- GPU / hardware acceleration failure — video decoder crashed, audio path still works.
- Browser ran out of GPU memory (lots of tabs with video).
- Codec issue — your browser can't decode the video codec but has the audio codec.
- Black-frame at start (the actual video starts a few seconds in).
- Driver issue — outdated GPU driver fails to render certain codecs.
How to fix it
- 1
Disable hardware acceleration
Chrome → Settings → System → "Use hardware acceleration when available" → off. Restart. Common fix when GPU-side decoding fails silently.
- 2
Try a lower quality
Gear → Quality → 480p. If 1080p decoder is failing but 480p works, your GPU can't handle the higher resolution. Stay at lower quality or update GPU drivers.
- 3
Reload the page
Resets the decoder state. Fixes most one-off cases where the decoder briefly failed but the rest of the player kept going.
- 4
Update GPU drivers
Windows: Device Manager → Display adapters → right-click → Update driver. macOS: System Settings → Software Update. Outdated drivers commonly fail on newer codecs (AV1 especially).

Try a different browser
If Chrome shows black-but-audio and Firefox shows everything, your Chrome's GPU decoder is the problem. Confirms the cause.
