My VAIO's HDD is broken, I buy an HDD and install Windows 10 myself without manufacture's driver (I use Device Manager to search drivers online). I find its sound of my laptop's speakers quite low. Before, I can hear audibly at 10% – 20% and never ever set to 60% – 100% because it too loud. But now, I must set to 60% – 90% to hear normally. How to fix it and where can I download drivers for my laptop? Thanks.
Information about my VAIO:
Model year: 2013
