LSI MegaRAID SCSI 320-1 (pcbx520-a2) is a 64-bit PCI SCSI RAID controller. We tested it in the 32-bit PCI slot and it works just fine.

Computer with a problem: HP Pavilion dv5227tx (I believe the solution is applicable to many dv5000 series laptops).

Sound device: Vendor ID 14F1, Device ID 5047

Windows 7 installs the driver but it is unable to start.
Downloaded sp35682 from HP Support site, this is a driver version 3.38.0.50 dated 03/26/2007.
Unpacked it and pointed the Driver Installation Wizard to the unpacked folder.
Driver installed fine but there were no sound from the speakers.
There was sound through the headphones.

I compared the registry settings from the original XP installation with the current ones.

The following key attracted my attention:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}\0007\Settings\OEM\DefaultJack]

I changed some keys back to the values they had on XP as follows:

“Wid13″=hex:01,02,01,00
“Wid14″=hex:02,00,01,00
“Wid15″=hex:0a,01,01,00
“Wid17″=hex:0a,01,00,00
“Wid1D”=hex:01,02,00,00

Restarted and bingo! Sound through the speakers!
