Re: Hp DV7 Speakers no worky

I see that you have sound problem because of not installing the correct drivers. If you need correct audio drivers, please follow these steps:
1. In the Run box type devmgmt.msc.
2. Unknown devices would be listed as such and marked out with a yellow question mark.
3. Select the unknown device or other device for which you need drivers and right click to access Properties.
4. In the Properties window click on Details tab and select Device Instance Id  or Hardware ID from the drop down.
5. An alphanumeric string like this PCI\VEN_1217&DEV_7130&SUBSYS_012F1025&REV_01\4&6B16D5B&0&33F0 is the identification marker for the device.
6. Please provide this number so that we can suggest the appropriate driver.
