YouTube videos too quiet — fix the volume mix
A YouTube video plays at much lower volume than other apps. You crank the system volume to maximum and it's still quiet. The audio is there, it's just inexplicably below the level of every other audio source.
Why this happens
- The video itself was uploaded with a low audio level (no normalization on upload).
- YouTube's Stable Volume feature is normalizing it down to match a target loudness.
- Tab is muted at a level below the system mixer (Chrome's per-tab volume slider exists).
- OS-level audio mixer has YouTube's app/tab at <100% while system is at 100%.
- Bluetooth headphones with their own volume control are at low volume independently of the system.
How to fix it
- 1
Disable Stable Volume
YouTube player → right-click → Stable Volume → off. This is a YouTube feature that normalizes loud videos down. On quieter videos it can't do much, but disabling it ensures you're hearing the original audio level.

Check OS audio mixer
Windows: right-click volume icon → Open Volume Mixer → look for the browser/YouTube slider, set to 100%. macOS: no per-app mixer but check Output Volume in Sound preferences. Linux: pavucontrol → Playback → set YouTube slider.

Adjust system master volume
If even at 100% the audio is quiet, the video itself is the cause. Use a volume booster extension (Volume Master, etc.) or system-level amplifier as a workaround.

Check Bluetooth output device volume
Bluetooth headphones / speakers often have their own volume control independent of the source. Press the volume-up button on the device itself — sometimes that's where the level is stuck low.

Try a volume booster extension
For consistently quiet videos, Chrome extensions like Volume Master amplify beyond 100%. Use sparingly — risk of audio clipping at very high boost levels.
