Check this,
My laptop makes the popping noise while the wireless card is disabled and sounds perfect without popping with the wireless card enabled. Try it, worked for me.
 
I'm having the same issues. If I wanted it to sound like vinyl, I would have never gotten rid of my 1200's. I'm using two different external sound cards.

M-Audio - I get Pops and Crackles
Numark DJIO - I get something I don't quite know how to discribe. The sound degrades so much, it sounds like a tamberine.

I have replaced every cable and connection. This is a new machine that is running XP service pack 3. After reading this whol post, I'm going to try checking my USB drivers and see what happens.

This is why I still use CD's for my events.
 
I had the same problem and it is a USB latency issue. Has nothing to do with the actual sound card. I have a Dell XPS that works incredibly if I use the onboard sound card. The minute I use my Behringer BCD 3000 I get that pop after a few hours of mixing. Not sure how to fix it. I just gave up on using the ASIO and used the onboard sound instead. Can you do that?

Some bright engineer out there needs to come up with a tool that you can plug into a laptops usb or hub and it will give a green or red light on different usb things like latency , power level, etc. I have an almost too old powerbook pro mac and I found out the hard way that there was not enough power to power up a VGA to Video scan converter I wanted to use.
 
It can hardly be a pure coincidence that I who also happen to have a Hercules RMX and a Dell 9400 Inspiron is experiencing exactly the same thing.

This thread together with my own experiences made it pretty obvious that the popping was somehow related to the graphics. As long as I had VDJ minimized I got practically no popping even when fiddling around with the controls on the RMX. And just as stated before the popping seemed to increase when moving the VDJ window during playback.

Also changing the ASIO buffer size as suggested in other threads had no apparent effect whatsoever.

Because I'm using Win Vista(?) and had the 9400 Inspiron's native ATI Radeon card replaced with an Nvidia card, I wasn't able to use rtrinidad's hardware acceleration solution. However, decreasing the color depth from 32-bit to 16-bit seemed to make the popping decrease. Finally I was just now able to make all the popping virtually disappear by forcing my computer to switch to a much lower resolution whenever VDJ is running (here from 1920 x 1200 to 1280 x 800).

Hardware:
Dell 9400 Inspiron
Intel Core 2 Duo T2400 @ 1.83GHz
1,5 GB RAM
NVIDIA GeForce Go 7800

Hercules DJ RMX
 
So just summing up...

To fix the popping problem, try:

1. Check that your drivers are up to date, without trusting device manager.

2. Check that it is not a ground loop.

3. Check that it is not due to other hardware by removing it and seeing if it makes any difference.

4. fiddle with the performance settings and disable safe mode.

5. Turn down hardware acceleration.

Remember: The popping sound in most instances seems to be caused by some kind of interfereance between digital devices; try whatever you think might eleminate this.
 
Basically yes. Generally the popping noise is caused by a latency issue so try disabling devices in device manager, then if that doesn't help, try the performance settings. Then check the computers manufacturer for the USB drivers and update them anyway.
