RE: How do i fix the sound on my lenovo laptop? ok so i enable my audio device on my lenovo laptop and it says the speaker and volume works good but when i use skype theres sound but when i watch a video on youtube theres no sound and so i need help fixing this sound? P.S. i have windows vista.f all else fails, go to control panel, system, device manager and find your audio card driver. Right click-uninstall and restart your computer. Once rebooted your sound drivers should re-install automatically. Good luck.
