HOURS AND HOURS..... STILL no solution to this crackling audio in e1505 with USB sound card

Hey guys,

I am in desperation currently with this problem. Let me explain my setup first.
I have the Dell E1505, 2gb ram, ATI X1400 mobility, 1.66ghz duocore processor, about 2 years old.

I recently got fed up with the onboard sound as I have taken a hobby up in purchasing high fidelity headphones. This led me to get a M-Audio Fast Track Pro which is an external sound card with a separate headphone amplifier. I basically used this sound card as my sound card as opposed to the sigmatel audio that's in the computer.
Everything was great but i found out that everytime that I did anything graphics related on my computer (blow up an image, scroll down a webpage, minimize a window, etc) that there would be a crackle/static that comes from the sound. It got reallllly annoying so I tried finding a solution but really could not.

One method was to unplug the AC from the computer and run on battery power. This magically worked! I didn't have any crackling. So basically I found out that the problem was that there isn't enough power going to the USB. I checked my IRQs and found though that there was no interference with the USB slots though.

After hours of research and more experimenting, it seemed like the gfx card was what really was sucking the power from the soundcard. I therefore uninstalled the X1400 drivers that I was using (omega) and tried to use the card on a low resolution. It worked! The moment I increased the resolution though, it seemed to toll the gfx card and the crackling happened again. I installed the stock drivers, still a problem exists.

I then thought it was a compatability issue with the M-Audio. I promptly sold it and got a Nuforce Icon Mobile USB DAC/Amp. SAME PROBLEM! Help me please what should I do? How do I get rid of this crackling?? How do I quit the gfx card from sucking all the resources from it?

please help me

*btw, I tried to use a powered USB hub... still no resolution

 

Instead of uninstalling the gfx drivers, try disabling the graphics card. This will only work if you have a built-in intel solution, which is quite a good probability. Have you checked each of your onboard ports to see if their output is the same. It sounds like you compared battery/non-battery, but not each. I have found each mobo and port are different and have variations of power on and off and to what degree. Also, have you tried using another ATI driver? Possibly trying a Linux Live CD or another Windows OS may prove another level of information. Could be some kind of system driver is installed incorrectly? Good luck. Those are basically out loud brainstorming ideas, so who knows what is the absolute solution.

 

Try removing the intel matrix drivers if you have them.

 

I had cracking audio on my new E6400. i found out it was caused by IRRT being enabled it is ok with the dell image, but installing another OS on there is a no go without drivers installed. since i couldnt be bothered with researching, and i didnt have a 2nd hard drive to use IRRT with I desided i didnt need it. reverted to stable ATA and still scoring exactly the same on benchmarks compared to the Factory Dell image/IRRT.

You need to find a few things out.
Do you have IRRT? is it enabled in your BIOS?
If so, ask yourself do you want cracking audio or do you want to reinstall your OS?

If you would rather Reinstall your OS than have cracking audio forever, disable IRRT - and enable ATA (should be around Hard drive options)

Install your OS again.

im sure there is a way to inject drivers then change the setting in BIOS but im a Tech at work so i CBF'd researching. All the best mate!
