I hadn't, but I have now - problem still exists. The aformentioned High Definition Audio Device driver works well without having to disable C-states, and it still works even with the performance level set to Balanced. (but I am testing in High Performance mode)
I thought it might be the Waves MaxxAudio processing causing the latency, but I have now tried Kevin Shroff's modded Realtek driver , which removes MaxxAudio - it still has high latency. Back to the Microsoft High Definition Audio Device driver.
@skip198 how is your experience with the microsoft driver and Kevin Shroff's modded driver?
PS: I've now found that I've now found that the latest 9560 BIOS causes __seconds__ of delay because of hundreds of SMI interrupts. In this process I've made an SMI counter tool for windows

Did you try disabling CPU C states in BIOS?
