Windows 7: No 5.1 on CMI8738

What has ram anything do to with sound????Its just that the driver(it doesnt matter that the chip is the same)isn't for this card.....The driver from cmedia site is working fine except theres no 5.1

Soundblasters, Hauppauge Tuners, and several other PCI solutions have trouble under 64-bit Vista and 7 when over 4GB of RAM is installed. The reason? PCI cards map portions of their address space into RAM. More than 3GB of flat address space was unheard of when the cards were designed so they map the card into the 3-4GB space. Since Windows is using that space too you get a conflict.

Try this -- run msconfig, under boot tab, advanced options, temporarily limit maximum memory to 3GB and reboot. Uninstall and reinstall the driver software and see if that fixes it.

I did as you told and removed 2 gigs....same freezing problem(with the drivers Diamond drivers)

Seems there are several varieties of that chip. Open Start, type devmgmt.msc and press enter. Expose the device you're having issues with and double click it. Choose the Details tab and then the Hardware Ids from the drop-down. Please post that data here.

Pci\ven_13f6&dev_0111&subsys_011113f6&rev_10
pci\ven_13f6&dev_0111&subsys_011113f6
pci\ven_13f6&dev_0111&cc_040100
pci\ven_13f6&dev_0111&cc_0401

Uninstall anything from control panel related to any drivers you've tried then remove that device from device manager and make sure to check the box to "delete the driver software". Then try installing this:

It has all the port assignments in the inf file correctly setup for Windows 7.

Rear and front are working now but...No sound from center or woofer(in test or any program that supports 5.1).

Multichannel is working so it must be a Xear setting now. Might help to ensure that Windows sees all the jacks. Click the volume control in the taskbar tray (lower left of the screen) then click the speaker icon. Make sure the jacks all show up there. If not you might be in 4-chan mode in Windows not Xear.

Strange its seeing only L/R

Right click volume control in tray select playback devices, speakers, configure and then you should be able to set 5.1 mode therein.
