Why? Because plenty of people are using a similar setup (albeit not identical) with no problems.
The problem is specific to your setup and could be:
1. A defective hardware component or cable (either within or outside of the computer).
2. An unsatisfactory software driver.
3. Conflicting software
4. Interference from an external device (something transmitting waves or a pulsing electrical device).
You need to test for the fault at different configurations of your setup. Start with the easy tests first. For example, disconnect everything from your computer except for keyboard, mouse and the USB audio interface. Ensure you have no background tasks running. Open a blank Ableton project, drag operator onto a midi track, create a midi clip, insert notes using the mouse and play the loop. If you experience crackles (and make sure to listen over headphones and speakers) you could download ASIO4all and use that instead of the Saffire drivers. If the crackles still persist you can disconnect the USB audio device and test using the motherboards onboard audio device, etc.etc. This testing method should help to eliminate suspects and finally identify the root of your problem.
First off I should apologize for the post made earlier, I wrote it when I was pretty tired. I have told myself not to post anywhere on the internet when drunk or tired but when Im drunk or tired I like to rebel against myself.
In response to you and to eyeknow:
Microsoft has admitted in the past to there being issues with external
usb audio cards and not fire wire. I overlooked that the op is using a fire wire interface.
To my knowledge Microsoft has released a hot fix for Usbaudio.sys for every version of Windows starting with xp. Its my
opinion that the problem still exist with external usb audio cards and my intuition tells me it also exist with fire wire. There are too many cases of a person using an external device with Windows, and having white noise burst and crackling when using these devices, for there not to be a problem within Windows itself.
I understand that faulty hardware or bios settings can play a role, the pci latency timer could be set too high within the bios but, the op has stated that he has tried all of the suggestions you posted regarding testing the hardware in earlier post. For some one that has the knowledge to build their own pc these suggestions are fairly common knowledge.
Using asio4all in place of the manufacturers driver is going to do nothing, the op would still be using an external device with Windows on the same machine. Asio4all only makes sense when a user is using an on board sound card.
Also a "generic cause" using Windows instead of another operating system can very well expose the cause if the problem is within the operating system.
I do understand that some people are using Windows systems and external devices with out problems, I have never met them but I have heard that these people exist. When I hear that people are getting along just fine using Windows I suspect that they are either using a high end pci card,simply using on board audio with asio4all or they did a tweak a long time ago and have not upgraded anything including software since then.
The problem with white noise does not seem to happen when using on board audio or pci devices and its my suggestion to people who build their computer to use them over an external device.
I also understand that some people have seemingly fixed the problem by following online "tweak your windows system for audio" guides but I feel these fixes (if they even work) are only temporary and the problem will come back with a software or hardware upgrade.
Should you really even have to tweak an operating system to get it to record and play audio properly? This is another indication that something is wrong with Windows and professional audio is not taken seriously nor is anywhere near a priority for Microsoft. I feel that Microsoft just don't get that many people use their computers to be creative instead of for constant consumption.
If there was no problem with Windows why would a company like Apogee chose to go mac only and lose all of the revenue from the pc customers.
Look on the pro tools forums under windows, there are constant unsolvable issues with either the mbox or avids fire wire hardware using Windows.
The only real fix is to either use a mac (I never have had a problem using an interface on my macbook) or to use a high end pci card or on board audio. If you are using a Windows machine and experiencing problems I suggest either sell the interface and get a pci card or only use the interface to record and switch to on board audio for all monitoring and editing.
I don't have a solution but the whole reason for me posting here is because I would like more people to approach Microsoft with these issues and let them know a problem exist that they need to fix and if they cant fix it more people will be dropping Windows for pro audio use.
