Help on setting up my new S4
I’ve just had my S4 delivered this morning. Got a bargain deal from Juno Records of £499 with the official flight case for free 
Anyway, just hooked up to my laptop, installed Traktor and ensured everything was installed and up to date. However, not plugged in speakers yet. Was listening through the headphones whilst having an initial mess about.
I noticed that I’m getting some clicks and pops, mainly noticed when turning an effect on (I think). Any ideas?
My laptop in a 2010 Sony Vaio with a Core i3 2.26GHz CPU, 8gb RAM and a 500GB Western Digital Black 7200rpm hard drive. I’ve also switched the audio interface in Traktor options to use the S4 but not played with any other settings other than default ones yet.
Check out the sticky thread at the top of this sub-forum by smiTTTen about his windows prep for the S4.
I ended up going with a dual boot system, running the script from the afore mentioned thread, and other tweaks I can’t remember.
There is also a sticky and a large thread at the Native Instruments forums on the same subject.
To start with make sure your wifi is off, use the wall wart, turn off all other programs, and see if that helps.
Also look into your latency settings, you may have to raise them.
Hope that helps 
Got mine from Juno on eBay and only got a decksaver… I tried to check Juno’s main site too, but they have two listings and google sent me to the wrong one with no extras. Damn 
One of the problems causing latency spikes I had was with the SD Card reader polling for devices. Basically, disable any devices in device manager you don’t need.
Had the same issue
I had to not just turn Wifi off, but completely disable the wireless controllers (all of them) in Device Manager.
You can run the Diagnostic tool (name escapes me) that gets installed and set the latency higher and buffer higher, but those still didn’t fix the issue. I downloaded a latency detection program from a link somewhere (I think buried in this site in a sticky?) and that told me disable wireless devices as well as other possibilities until you resolve the issue. NI’s diagnostic tool told me my computer couldn’t handle it.
Looks like your laptop should be beefy enough, and I tried every possible thing to get the pops to stop. Nothing worked until completely disabling the wifi drivers in the Device Manager. It’s a bit of a pain to disable and re-enable after using it, but damn fun once you get it all figured out.
Good luck
