If it's general sound on your laptop that is soft, you can try checking Control Panel > Sound > Playback > (Right-click your sound device you are using) > Properties, check if the volume is at 100, and try using the Equalizer enhancement and putting all the freqeuncies on max, and you can check your volume mixer.
If it is just youtube, try watching the videos in VLC, by doing this: http://www.thesofthelp.com/2009/08/how-to-solve-low-volume-problem-of.html

Look for the Volume Mixer icon on the bottom right of your screen in the toolbar near the time. It may be hidden so click the " If the Volume Mixer icon is not there, go to the Start Menu then click the icon for Control Panel. In the Control Panel window, select Sounds and Audio devices.Once in the settings for Sounds and Audio devices, there should be a checkbox for the option to "Place Volume Icon in the Taskbar." If no checkmark is there, click the box and then click on "OK". Now the Volume Mixer icon should appear in the taskbar. Proceed by clicking this icon to launch the control panel for Volume Mixer. From here, you can change the volume settings for your computer and specific programs. Be sure to adjust the Master Volume setting.
Go to control panel > sounds and audio device and have a look in there or click on the advanced button for the audio mixer in the mixer, go to options > properties and select mic click ok then turn up the volume on the mixer.
Have you tried going into the speaker settings? We'll assume with a new PC you have Vista installed, click the speaker icon on the right side of the tray, and selecting "Mixer" will enable access to volume control for the output devices and for applications.
If no speaker icon is visible To check the volume controls in Windows Vista, click Start and then click Control Panel. Choose Hardware And Sound and then click Adjust System Volume under the Sound section. The Volume Mixer window will open, and you should see volume sliders for Device and Applications. Click and drag the sliders to view the volume level percentages. If the speaker icons show a circle with a red slash, click the icon so the speakers are no longer muted.
Furthermore, you’ll want to double-check all of your master
volume and mute settings.
Go back to the Control Panel, click on Add or Remove Programs, look for 'Add/Remove Windows Components' and check if the media player is checked.
Most sound cards and on-board sound chips have their own software but the Media Player will suffice.
If it is checked, go to 'System' (in the Control Panel), then click on the Hardware tab, then Device Manager.
Go down the list to see if Sound, video and game controllers has a red 'X' showing.
If it does, then either the driver is damaged or the hardware itself has failed.
If it is only the driver, you can delete the exed item and try rebooting to see if Windows restores it.
If that doesn't work, the you may have a system board problem (expensive).
