The problem is defiantly either related to CPU spiking, which is largely related to the front side bus speed, CPU speed, and your amount of cashe. Another issue is the clocking on your sound card, and how much available RAM you have when running your audio programs. It could be all of these, or one of these. Many times I find that multiple factors contribute to degradation of audio performance.
Lastly, spyware and virus programs such as mcafee, and norton put a huge strain on your system resources, especially if you have real time protection on. Do some process of elimination and see. Post results for us.

Hereís more information on my Windows 7 64-bit audio problem. I have a head full of trials and processes, I will try to be clear and concise, but I may ramble. Bear with me:
I bought a new computer (3.46ghz quad core with 12GB RAM.) I loaded Office 2010 and foobar, and connected a network plug for my internet. I let the updates load. Next I plugged in my PS Audio Digital Link III for audio (itís a USB digital to analog converter) and then plugged in a couple external hard drives with my music (all in FLAC.) Started Foobar, selected my music, and the problems started there. I get an audio drop-out every few minutes, sometimes twice in a minute, sometimes not until 10 minutes. Totally random, and the drop out lasts a quarter second, itís like a skip. So my issue started right out of the box.
I load up DPC latency checker. Pretty much green bars all the way, average of about 300. It might peak at 1000 from time to time, but it doesnít correlate to the audio skip or a process turning on (according to task manager.) So my latency is ok, and Iím not seeing my drop-out corresponding to a rise in latency.
I do a clean-boot and turn off everything non-Microsoft. Still have the problem. I continue trying a clean-boot turning off virtually everything that isnít necessary. Still no fix.
(All this time Iím tracking Task-Manager to see if I can see a process turn on that corresponds to the drop-out. I donít see anything. I have task manager sorted by CPU usage, see no spikes, the numbers look like Iím running smooth. My CPU is idling between 93-96% when problems happen.)
In task manager, I start turning off everything one at a time until Iím down to barebones. The problem still persists. In task manager, I also donít see any nVIDIA processes running. I turned off a process called SeaPort, and that seemed to fix the problem for a long time. But it came back. I even changed the filename of seaport.exe so that it wouldnít magically come back on.
Iíve gone into Device Manager and disabled multiple items to no avail. I have turned off the nVIDIA sound drivers and two other sound drivers that were present. Everything except the USB codec that loads when I plug in my USB DAC. I have tried using the other two sound drivers instead of the USB codec, and they have the same issue.
I have the same issue whether I play music from Foobar or a CD directly from the CD player on the computer (I don't remember what program I used to play it.) I loaded up winamp to see if that had a problem Ė it does. I have set the buffer on Foobar to maximum, and tried various settings in between. I saw a thread where somebody was able to fix their [windows 7] problem by adjusting the sample rate on Foobar, but Iím not sue how that will fix audio from applications like youtube which has the same drop-outs. No, there is no affect on video, just audio.
Iíve tried to update various drivers, but windows says they are up to date. I havenít tried to uninstall/reinstall drivers because thatís getting a little too technical for me and I donít want to kill my computer. For instance Iíve seen threads where itís stated that nVIDIA drivers may not be too good, but if I uninstall my video card driver it seems that I wouldnít have any display to look at to reinstall it. Hope that sounds funny to someone. And as for sound card drivers, I donít believe I can update my ďplug and playĒ USB audio device. Iíve also seen threads about updating chipset drivers, that sounds a little too complicated for me as well. But if thatís what it takes, and itís a silver bullet, I can certainly Google it and figure it out.
No, I havenít tried windows media player yet. Not sure why, but it doesnít make sense that everything else is having issues.
I tried disconnecting my network cable, nope. I donít have any torrent software on my computer either. I did load Skype though, maybe if I unload that?
I have McAfee antivirus. I turned off the live scan portion and that didnít do anything. I think I turned everything off on it too, and that didnít do anything.
I donít have any ďcracklingĒ or static, just a quarter second drop-out that will drive you insane. And itís completely random.
Iíll end this by saying that I have been running USB audio through my old XP machine for four years without any issues. Sigh.
Thanks for reading this far. Hope this helps somebody, and I would appreciate any advice someone is willing to share.

Even though it's a new machine... is there a more recent BIOS update for the motherboard?
I have no sound issues but I'm running in 32 bit mode.
I have a lot of experience setting up windows machines for audio, the Win 7 machine I'm using now does very well, able to stream multiple sources... Youtube, Winamp, CD at the same time without glitching or dropouts but Windows 7 has been problematic for many.
With all of that memory try setting a "static" swap file, make the minimum and maximum size equal, 2 or 4 gigabytes should be fine.
Shut OFF Indexing on all drives, shut down any real-time virus checking including Windows Defender located in "Services" until you find out what's causing the dropout.
Since my machine is used for audio I've gone to extremes...but man... does this thing run great.
People get sick of seeing these so here's the last pics I'll post on the matter.
I have two virus/malware checkers (Malware Bytes and Spyware Doctor/Antivirus) and I run them manually.
You might take a look at your services to see if there's any nVidia or other useless processes running.

Other things I did to stabalize it all
removed the video-driver, restarted with VGA mode (for there is no more video-driver: ) and still the sound was bad. Feeling stupid, but almost feels like I have to install a fresh Windows all together : (
Last week I updated to Windows 7 Enterprise x86 SP1. The sound problem remained. Then I did a repair-upgrade, which did not change much.
Totally fet-up with it, I went to a recycle-firm and took an old PCI Soundblaster card (costed me Ä0,50). This greatly reduced all my problems!
BUT the problem still wasn't completely gone. Once in a while I still had interruptions, but nothing like mentioned before. The new interruptions were all caused by CPU spikes when playing (browser) video (chrome).
So I went on by uninstalling Flash Player. Only thing I could find for this, was the official tool. It only seems to remove a DirectX pluging - which I don't use.
I also updated my video-card drivers to the latest found on the NVidia website. Many versions had come by, so this might solve CPU-overload problems. Doesn't look like it, but shouldn't hurt either.
Then I started Firefox, and the CPU was just a bit less stressed (stress == more than 90% on my 3,0GHz HyperThreading, 2GB). than my Chrome is. So sound for videos was even better than with Chrome. So I re-enabled (in Device Manager) my onboard sound card. It had a bit more disturbances than the old Soundblaster, but was way much better than previously.
Finally, I got the CPU constantly at less <90% CPU for playback of web-videos. Both soundcards now give a stable sound. With the Soundblaster more volume and warmth - 50 cents well spent : > MAIN trick to stay under the 90% stress-free CPU usage, is BY CLOSING task manager - which I always have opened. It consumes 5 to 10% CPU too! Also, running Process Lasso in the background does not help - it reduces Firefox priority to below-normal.
Main conclusion (for now, that is) is that my problems are caused by a too high of a CPU load.
Main questions I am left with are:
1. why did it take me so long to solve this? ; PP
2. Shouldn't be a HP DX2200 with 2GB RAM be fast enough to play web-videos??? What processor should I have as a minimum, in general, to fluently do web-videos? Any practical feedback would be greatly appreciated...
ALSO: of GREAT interest when troubleshooting this problem yourself, check: DPC Latency causing audio stuttering, crackling
More system info: Avast 5 installed, but shields disabled. Enabling does not cause more problems. Network connection: mostly wireless, USB. Power options: min/max processor state is set at fixed 100% ++ wireless adapter at Max Performance ++ system cooling was active, now put to passive (I only changed this after fixing my problems, but it could solve yours). Active means:: always on, passive = cooling when needed.

Finally definitely provably and logically solved the sound stutter
And now I really solved it! I can even pinpoint it! No doubt, all sounds working smooth again, even with maxed out cpu.
All problems were caused by my USB Wifi stick. I already had disabled wireless lan in the past (as suggested by others), but this didn't fix it.
What fixed it, was downloading the latest drivers from realtek. I used my ISP's installation cd for the USB Wifi-stick (Online Internet BV, RTL8187b chipset on USB Thomson Link TG123g DSL36307020 wifi-adapter), with Microsoft Update. But that's not current enough.
I downloaded the latest driver here; Realtek .
After that, I could Youtube Fullscreen @ 720, in two browsers with fluent sound. Sure, CPU maxed out at 110%, and video image not-so-fluent anymore, BUT crystal clear sound. As it should! NO more distortions!
So all whom are getting really really really desperate... If you have Realtek Wifi chipset... Go check out their latest drivers, you might need them ; )
PS: most problematic audio device was the onboard High Definition Audio Device (hdaudio func 01 ven 10ec dev 0861 subsys 14627254 rev 1003). Which has, guess what, also a Realtek chipset! I'm downloading (sloooooowly) the newest drivers (dated Jan. 28-11) for my audio too, just in case, from here: Realtek
PS: As mentioned, some privacy tools can cause problems too! I solved my final connection problems not mentioned here, more in this link: http://www.techrepublic.com/forum/di...cussion-thread

Win 7 Sound Stutter
I suffered this for a long time with no fix and blamed win 7 and the sound software I was using ( amazing slow downer) the stutter was occasional with no apparent trigger -the fix was simple when I sorted what processes were running, I run AVG antivirus and Windows had also activated the Windows Firewall - I switched off the Windows Firewall and my problem disappeared. No other programs seemed to be affected and when I had the stutter the processor activity stopped completely.
