While out grazing the herd, I came across this handly little tweak for Creative sound cards. It seems not only did Creative remove support for Dolby Digital and DTS in their Vista drivers, but they also removed a few options for Windows Media Player 11 and Audio Environments, which are very handy for MP3 players or anything else routed through the Line-In socket. I have tested this method on all Audigy series drivers, but may work on other Creative sound cards such as Live! or X-Fi.
This tutorial will involve modding driver files and registry entries, so it won’t be suitable for all users. Try at your own risk, and don’t whine to me if it doesn’t work or turns your PC into an atom bomb! It will require that you have WinRar installed also. It also goes without saying, that UAC must be disabled. It’s also worth noting that “Allow Unsigned Drivers” must be enabled. To enable unsigned drivers, simply hold F8 before Vista starts to boot.
Firstly download the latest working Creative drivers. I used SBXF_PCDVT_LB_2_15_0002.exe (2007-05-10) . Once downloaded, right click on the SBXF_PCDVT_LB_2_15_0002.exe icon and “Extract to SBXF_PCDVT_LB_2_15_0002“
Once extracted, open your newly created folder and enter the folder named “wdm” and then locate the file “wdma_emu.inf“. Open this with Notepad.
Add a semicolon “;” in front of the two “Catalog…=…” entries (Otherwise Windows will read the digital signature, see that the file was edited and refuse to install it) For example CatalogFile.;NTX86=wdm_emu.cat and CatalogFile.;NTAMD64=wdmemu64.cat
Now scroll down the document until you reach the “[Live2K.Interface.Topology]” section.
Add “MSSysFX.AddReg” to the “AddReg=…” entry. (It should then look like this) AddReg=Live2K.Interface.Topo.AddReg, CTSysFx.AddReg, OEMSettingsOverride_Speaker.AddReg, MSSysFx.AddReg
Save the document, and then run the setup file located in the SBXF_PCDVT_LB_2_15_0002 folder. Don’t forget to use the Dolby and DTS Fix before you reboot either. You don’t want to lose that at any costs!
Upon reboot, you will find that all enhancements are available. An extra tab will appear in the “Speaker Properties” dialogue, allowing for various sound compensations and adjustments. Good Luck!
