I have a PC which originally had a DH67CL and a Creative sound card. I bought a DZ68BC to replace the DH67CL. All but one of the other components are the same: i5-2500K, Crucial Ballistix Tactical RAM, sound card, and 650W PSU. The only exception is that I replaced the hard drive with a 730 SSD and used the WDC hard drive as a data drive. Sound-wise, the system was fine with the DH67CL.
Now, however, after the system goes to sleep and wakes up, the sound is crackly and distorted. A reboot is necessary to remove the noise. Obviously the sound card could be the source of the problem, but it's equally likely that some device driver is to blame. I did remember to disable the on-board sound. The BIOS is 28, so I cannot blame it on Ivy Bridge BIOS. I am not over-clocking this system. The chipset mode is AHCI for both SATA controllers. I originally installed RST, but I uninstalled it.
The only thing I can think of is to revert the Creative device driver back to the one intended for Vista/7 (I was using the newest one for Vista/7/8), but Creative device drivers usually don't revert cleanly in my experience. Has anyone run into this problem? Could the fact that RST was installed and then uninstalled have anything to do with it? If no one has any ideas, I'll wipe the SSD and reinstall W-7, only with no RST and the older device driver.
