How can I restore the sound after upgrading to Windows 7?

I, like many others, have lost my Output Audio Device after converting my laptop from Windows XP to Windows 7. There are no drivers, devices, controllers, etc. I’ve run the updates, downloads, installs, dxdiag, PIRIFORM SPECCY. I can run video, but with no sound. The specs that I can find are as follows:

HP Pavilion zd8000 (EC308UA#ABA) Bios Ver 1.00PARTTBL
Old op system Windows XP 32-bit
New Windows 7 Home Premium 64-bit
Device tree says ACPI x64-based PC
Motherboard is Quanta Model 3082
Version F.33
Hard Drive TOSHIBA MK1031GAS ATA Device
Partition #0
Partition ID Disk #0
Disk Letter C:
File System NTFS
Size 93GB
Used Space 57GB (61%)
Free Space 36.5GB (39%)

Also I never got an error when installing Windows 7 saying that the file system was NTFS, and I can’t redo anything about that. What else can I tell you or should I just send a cc of the .txt file with all my dxdiag and speccy? I also had a heck of a time getting Google Chrome to install, and now can’t be seen or connect to the Homegroup my husband set up so we could share printers.
