Difference between 2500k and 4770k sleep states?

I'm having a wake from sleep problem with my 4770k that I didn't have with my 2500k. Basically when the 4770k wakes from sleep the audio is distorted and can only be fixed with a power cycle of the Presonus Firestudio Tube (my audio device) or a computer reboot. It definitely sounds like a buffer overflow issue.

I know that the desktop Haswell doesn't include the new deep sleep state but I'm wondering what exactly are the differences between Haswell and Sandy Bridge desktop sleep states?
 
Yes I have a 3TB Seagate Drive in a USB 3.0 port. Would that be connected to this issue?
 
Presonus Firestudio Tube via Firewire using a TI based Firewire PCI card. I've been running this system with a different motherboard and CPU (the Sandy Bridge rig in my sig) for the last 3 years. No problems waking up from sleep. So I was thinking it might be something with the Haswell "deeper sleep" that might be causing my problem. But now I'm thinking that the desktop Haswell doesn't sleep any "deeper" than Sandy Bridge?
 
Hmm, not sure. I was wondering if it were an USB device because the initial revision of haswell motherboard chipsets had USB issues when waking from sleep.

any controller driver settings / updates for PCI bridge?

I am having a weird sleep issue with a c2 haswell chipset. I have a vengeance 1500 usb headset. When my computer comes out of sleep it does not detect the headset and plays through my speakers instead. Have to pull out the usb cord and plug it back in to get it work again.

I think the problem that we're both having is Haswell going to sleep is shutting off contact to various peripherals and then not establishing proper context with them when waking up. I have a feeling it's a driver issue where the device needs to be internally power cycled when Haswell comes out of sleep.

Curiosity - any IRQ sharing? - same for USB issue above as well

And do you have anything like "deep sleep" enabled in BIOS?

Now I'm thinking the issue here is that my MSI R7770 video card is right next to the PCI firewire card that drives the audio interface. When I move the mouse around the screen in Chrome I get a lot of popping and clicking. I'm going to pull the video card tomorrow and use the IGPU and see if I still have the problem. I'll have to get a PCIe Firewire card if that's the problem and I need to move it away from the video card.
 
I figured this out. The noise I'm hearing is EMI emitted by the video card and being picked up the the PCI Firewire card that is driving the outboard Presonus Audio Interface. They are in adjacent slots. When I move the mouse the video emits EM and the PCI Firewire card picks it up. I pulled the video card and used the IGPU and the noise went away. When I first built the system I was using the iGPU, then installed the video card and I mistakenly thought the noise was coming from wake from sleep when it was there all the time with the video card. Just worse in some apps than others. Chrome for some reason was the biggest offender.

My slots from top to bottom go PCIex16, PCI, PCI, PCIex4. Unfortunately the video card won't fit in that bottom slot so it looks like my options are to try and shield the video card or move to a PCIe Firewire card to get one slot farther from the video card. Since this EMI is proportional to the inverse square of distance a half inch could make a big difference. First I'm going to try some aluminum foil on the bottom of the video card just to see if it makes a difference.

Any suggestions? Anything else I'm not thinking of?

Wrap your sound card in felt, with aluminum foil around that?
