Motherboard problem or only Audio problem?

[Johny999]

Welcome everybody ! I am new member and I'm writing to you because I have problem with ma HP Pavilion dv6500. My laptop was imported from USA and I have problem because when I instaled Windows 7 Pro 32bit or Windows 7 Ultimate 32 bit I haven't sound 🙁 On volume control option is No Audio Output Device is installed. There is no option in device manager about videos, games, audio. I don't know what drivers should I install because I'm downloaded many of them and any are working.
Please help me and sorry for my English

Hi,

I would start checking in Device Manager under "Unknown Devices" first. If there's an Unknown Devices in Device Manager it could either be one of them there. Right click on the unknown device and go to Properties then click on Details and from the drop down list select Hardware ids, that's what you'll use to identify what those unknown devices are. If you need the drivers you can download them from HP support site.

Hello, thanks for answer but unfortunately I don't have any unknown device in device manager 🙁 a drivers from HP site didn't work, I downloaded all of them and any driver audio work on my laptop.. That BIOS update solve problem ? In BIOS i have not any option about audio. I tried fix it by fix.reg in regedit and didn't work. Any ideas ?
