Audio 8 CPU Spikes Posted on: 30.05.2012 by Cole Maroto hey everyone, i recently started digital djing again with tsp 2.5 and i'm having some issues with my audio 8 and cpu/latency spikes. it's like clockwork. when i have the audio 8 plugged in and traktor running (even just idle), i get cpu spikes to 25% every 10 seconds or so (all other times cpu is at 0-1%). when running the latency test within traktor i get the same results with latency usually hitting around 400 every 10 secs. it still stays in the green mostly, but it seems like these semi-quick spikes are causing some minor audio issues...almost like a slight pop in kick sounds, which is driving me nuts. this issue only happens when traktor is running and the audio 8 is plugged in. i'm currently running in external mixing mode with an x1 and an old 2 channel numark mixer. here's my laptop specs: hp dv6: i5 processor with 8 gigs of ram running windows 7 64 bit. brand new laptop, less than 1 month old that i am ONLY using for traktor. i have followed most of the pc tune up steps and have some backround services disabled, wifi disabled, virus software disabled, etc. i have tried uninstalling the audio 8 driver (which was loaded during the tsp 2.5 install) and installed the newest driver from the ni site (which ended up being the same one). i have tried a different usb cable and every port on my laptop with no luck. i have also tried every latency setting in traktor and it's the same result. i tried unchecking multi-core support but that ended up making the issue worse and generally spiking to about 40% cpu load. do you guys believe it may be an issue with the audio 8 itself? i'm about to pick up an s4 in the near future and really hope that this issue will not continue with that hardware. what do you guys believe? thanks for taking the time to read this and any insight would be helpful.
Cole Maroto 09.10.2012	Originally Posted by wrigh_a I can replicate this issue very easily on my fully optimized win 7 32bit machine. I have every non essential service turned off (www.blackviper.com) and no anti virus etc. with an audio 8 or audio 2 connected and trakor running at idle my cpu spikes to 50% every 15 seconds. this is better is I use the old 2.0.15 driver instead of the 3.0.3. This is without doubt the audio sound card as I have tested with other sound cards and don't cause the same spike. Also tested with traktor 2.03 and latest 2.5.1 same issue. Has anyone found a way round this? my concern if that lets say you load a track at exactly the same time as the spike happens could cause issues. Has anyone raised a support call with NI? win7 32bit sp1 4gb ram ssd drive TSP2 audio 8/audio 2 to be honest i haven't really looked at my cpu to see if it's still spiking when i use the vci-400 or my audio 8. after doing more research i found that the pops i was hearing were actually an issue with keylock in traktor 2.5 so once i turned that off the sound artifacts went away. it was throwing me because they seemed to happen at the same time as the spikes, but that could have been coincidence. i was never able to get rid of the cpu/dcp spikes entirely but i found that disabling the acpi battery cut my dcp spike levels by almost 70%. I haven't noticed any issues when playing via my audio 8 or vci for long periods of time so i stopped being concerned about minor dcp spikes that stay in "green" levels. i don't recall if my cpu spikes lessened. i never made it as far as a support call with ni due to my past support experiences with them and almost every company ever. i would rather try everything i can on my end with research first. have you tried running a dcp latency tool? i thought that the audio 8 was solely the issue but found that i was getting yellow dcp spikes even without it plugged in that coincided with the audio 8 cpu spikes when it was plugged in.
Cole Maroto 01.06.2012	Originally Posted by Scaper7 I've only experienced this cyclic CPU spiking with NI interfaces. Does your CPU still spike using another interface? yeah, my research is kind of telling me the same thing about ni cards on some windows machines. i don't really have another interface to test...well, if i can find my old bcd3000 i can try that out and see. i can also test with my laptop's built in card, but i don't believe that will make the cpu spike. so what other interfaces have you used with no cpu spike issues?
Cole Maroto 01.06.2012	Originally Posted by bumtsch That was the first one I bumped into : http://support.microsoft.com/kb/981214 There's also this, but again the results are hit or miss (mostly miss!) http://support.microsoft.com/kb/2529073 (you can pre-check by running this http://code.kliu.org/.etc/7601usbfix/) thanks for this. i tried some stuff last evening and ended up getting the dpc tester. i found that i was getting dpc spikes generally around ~450 at the same 15 second intervals even without the audio 8 plugged in, but no cpu spikes. occasionally those dpc spikes would hit the yellow around 600-700. i looked in the resource manager when the audio 8 was plugged (with traktor running) in and my cpu 0 was hitting 100% at the 15 sec intervals with cpu 2 hitting about 30% for a total of the 25% cpu. i ended up adjusting some power management settings i missed and disabled usb selective suspend. those didn't really seem to help. disabling the acpi battery gave me the most dpc improvement. without the audio 8 the highest dpc i get is around 150. with the audio 8 and traktor running a couple of tracks and effects it's peak was 300, maybe 350...so it's much better now, though i still do get the cpu spikes. that's okay with me as long as the audio doesn't suffer. from my research it seems as no one has really found a way to stop the cpu spikes. i believe i was still hearing some slight pops at a 128 buffer so i changed it to 256 and i didn't seem to hear any audio issues after that. if they spring up again i will try to run that ms hotfix.

Addie Engbrecht 09.10.2012	Use this Driver instead. It's dates back before NI changed their drivers, and after they did change, a lot of people that never had issues, all of the sudden did. http://download.native-instruments.c...stamp=5074c393

Cole Maroto 03.06.2012	i just ended up ordering the vci-400 ege so it will be interesting to see if the cpu still spikes.
Delila Vandommelen 02.06.2012	I had no such issues with my ESI Gigaport HD. It also had no inputs and no timecode support whatsoever, so using it is out of the question now :P

I believe it might also have been happening with XP SP3... now that would have been interesting to remember.

Since switching to TSP 2.x which increased the load somewhat, I've bumped my usb buffer from 1ms to 2ms (256 samples of audio buffer for a total latency of about 10/11ms @ 44k), the load still plays the yo-yo but no audio glitches to report.
