I was watching a movie on my lCompaq 610 when the sound suddenly went down. I tried restarting without any success. I have windows 7 which have been working quite well with the laptop.
Solution
Uninstall the supplied sound card driver via add/remove programs, then reboot the laptop.
At startup, it will use a generic driver for the sound and it should work without any problem. Don't reinstall the Compaq Sound driver.
