Hello, I’ve been using Traktor Pro 1 for some time now without any problems with latency, but for some reason, I seemed to be having some latency issues during the last gig I played a week ago. I hadn’t messed with ASIO4ALL, installed any new software, etc. so I have no idea what’s been causing this, but Traktor’s CPU has been flaring up fairly randomly (yet frequently), occasionally entering the red. Sometimes this is audible, other times it’s not. I’ve tried the following to fix the problem:
-Reinstalled Traktor
-Reinstalled ASIO4ALL
-Did a system restore to a time when I wasn’t having latency issues
-Have configured ASIO4ALL with high latency, low latency, and everything in between. 896 seems to be the lowest I can go now, as opposed to when I was running at 512 smoothly
-Disabled my NVIDIA graphics card, Bluetooth, WLAN, ACPI Compliant Control Method Battery
-Updated my BIOS
-Turned off USB power managment
I also tried setting my audio device in Traktor to my computer’s soundcard, rather than ASIO4ALL and still got the same results. At this point, I’m completely at a loss as for what to do. I’ve freed up a bunch of space, defragged my laptop, etc. Nothing. Any advice would be much appreciated, as I have a gig this Friday and am kind of losing it. Thanks.
I also just ran LatencyMon and found acpi.sys giving me a 1.2 highest execution. But I’m not able to disable this file via BIOS or Process Hacker. However, I’ve also read a bit up on it, and some people seem to think it might not be a good idea to end this service, anyway.
I also tried disabling my internal soundcard to no avail.
I ran into a similar problem with my ThinkPad Edge 14 and Traktor Pro 2. I’d get periodic dropouts every ~30-60 seconds that would last 3-5 seconds each. LatencyMon determined acpi.sys was the biggest offender.
In my case, the problem was solved by uninstalling 2 drivers… the Intel Storage Matrix drivers and Synaptics Touchpad drivers. I didn’t use the Intel Storage Matrix stuff (usually used for RAID, where my laptop only has a single drive anyway) and the standard Windows mouse pointer driver worked just fine. After pulling both of these, boom, no more acpi.sys latency and I can use both jogwheel scratching and DVS with 192 buffers.
Check your drivers, uninstall anything you know you can get rid of.
I uninstalled my touchpad drivers and nothing new happened; and I don’t seem to have anything similar to the Intel Storage Matrix (or any AMD equivalent).
I just sprayed a bunch of compressed air into the vents/fan, which didn’t seem to do anything. And correct me if I’m wrong, but the CPU in Traktor doesn’t correlate to the actual CPU of the computer, but to audio latency.
Also, nihardwareservice.exe seems to crash whenever I remove something from a USB port. Possibly related?
I’m not able to disable ACPI in my BIOS–it seems that my BIOS is fairly limited in terms of what I can do in it. I’m able to check the general system info, change boot order, run diagnostic tests, etc., but there’s nothing about ACPI.
Whoops, totally spaced on the hardware information. Here’s my specs:
Windows Vista SP2 AMD Turion 64 X2 2.1ghz 4 GB RAM Behringer U-Control external soundcard Conexant High Definition SmartAudio 221 internal soundcard M-Audio X-Session
I use the external soundcard to plug into the sound system and then plug my headphones into the laptop’s headphone jack.
If I don’t use ASIO4ALL, nothing comes out of my headphone jack and I can only play music through my external soundcard. Basically, I use it for headphone cueing. Windows doesn’t by default allow you to divide up where audio is going–ASIO4ALL solves this problem.
I realize that, but task manager indicates that my laptop’s CPU isn’t really having any trouble handling Traktor–hence the issue seems to be purely audio-based.
Just disabled it–Traktor’s CPU is still flaring up.
I also just attmped to do a “clean boot” of Vista (see How to perform a clean boot in Windows - Microsoft Support) and the problem still arose. So it doesn’t seem like any Microsoft services, startup items, etc. are at the root of the problem.
Reformatting should be done semi regularly to keep your computer free from crap. It takes about 2 hours, costs nothing and makes your computer feel brand new.
Computers accumulate crap, that’s what they do. New updates leave old crap behind and urgh. Also everything gets horribly fragmented over time and it’s never completely solvable.
