I was surprised to learn that Intel indicated that the DP35DPM board is Window 7 compliant. Intel neglected to post a driver
for the "IDT audio" chipset and for the "PCI Simple Communications Controller". Here is a trick and it will work, provided you have the original disc that came with your board. Place the disc in the drive, then enter your device manager. Look for the "PCI Simple Communication Controller", right click, and choose "Update Driver". Set it to browse the drive where the disc has been inserted. If memory serves me correctly, these drivers
are also included in the "Intel Desktop Utilities" program as well.
In reference to the default audio driver that is included in Windows 7, does absolutely nothing but provides sound. The reason for this, what I call screw up is because they are eliminating the "Stereo Mix" feature. Why you ask, because apparently some people are making digital recordings and selling them for profit and naturally this violates copywrite laws and goes against RIAA. So the only way to get this feature back is to either revert back to XP or Vista? No, you can have it in 7 as well. Download the driver from the Intel site for Windows Vista. Click on the auto exec file. It will ask you where you want to extract files, usually the c: drive. Instead, choose to download those files to your "Download" folder. After that, you stop the install. Go into your device manager, choose the "High Definition Audio". Right click on it, and and choose "Update Driver". Again, browse for the file, located in the "Download" folder. Once installed, reboot. After reboot, the IDT control panel will pop up. Do not attempt to change any settings in the IDT control panel. Instead, click the "Hardware and Sound" in the Windows control panel/ and select "Sound". Make you adjustments there. The IDT control panel is good for volume settings and turning Dolby Digital on and off. Now I did this prior to the installation of the SP1.
I have spoken to legal represtation on how Intel neglected fullfilled their part of the obligation in reference to this particular product. Trust me, I will keep you posted on the outcome.
