Right, so I get fairly frequent occurrences (windows 7 64 pro) when the audio kindof stutters for about half a second. Like it's in a loop of about 1/10th of a second, repeated 5-10 times. Happens while gaming, or while playing music (doesn't matter what player I use).
Research led me to crappy realtek onboard audio drivers, so I installed a xonar and disabled the onboard audio.
Xonar exhibits the same symptoms.
Gigabyte GA-55 UD3P motherboard.
Sapphire HD5770 with latest catalyst drivers.
I also have a 4 port generic USB PCI card installed.
Have changed power profiles to disable power saving on the CPU and PCI buses, no difference.
Upgraded onboard Realtek GBE driver to the latest, no difference.
Anyone have any other ideas? This is annoying, to say the least...
