Question about HP (400745-001) Sound Card
Go to the HP support site. I've got the link for your laptop
Choose the operating system you use and under Hardware - Audio choose the latest audio driver adn install it.
Incase you feel uncomfortable using that link here is the link to the HP support site home page
Enter your model number in the search box and choose "Download drivers and software (and firmware)" and hit search.
I hope this helps.
