Just installed Win7 Pro on my dv1000 (specifically dv1680ca) and I have no sound. I had to initially install a driver from HP's website (only drivers for XP and Vista were available) for windows to see that I had speakers at all, not it thinks I have sound (sound animation in taskbar), but no sound. I do get sound when I plug in my headphones, but nothing from the speakers. The same problem came up with Vista, but the driver seemed to work that time. I was browsing their website, and this link seems to suggest that my computer won't be supported with windows 7? If that's the case.... DAMMIT!
