Massive latency problems

Recommended Posts

Okay so not sure where to start.  After installing Windows 10  Sonar has become almost unusable.  And for the life of me I can't see what is wrong.  My computer is a i7-4770k and I have 16gb of RAM.  This setup worked fine with Windows 7 (though I still think there was something off with that setup as well).  This is what LatencyMon says "Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates. "  

Please help

Thanks!!

What is your sound card?

Are you using WiFi rather than a wired network?

Have you set power setting to maximum performance?

Have you disabled Power management on your USB ports.

I am using WIFI

Power is set to maximum performance

All USB root hub power are disabled

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed:                                   3506 MHz

Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs):   1451.70
Average measured interrupt to process latency (µs):   5.041415

Highest measured interrupt to DPC latency (µs):       1419.40
Average measured interrupt to DPC latency (µs):       2.085342

_________________________________________________________________________________________________________
REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

 REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count:                 cakewalk.exe

Total number of hard pagefaults                       2578
Hard pagefault count of hardest hit process:          446
Number of processes hit:                              41

These are big ones -

Have you done that?  Also win10 has a lot of background tasks running by default. Disable the ones you don't need.

To see which apps have permission to run in the background, open the Start menu or Start screen and select “Settings.” Click or tap the “Privacy” icon in the Settings window.

Scroll down to the bottom of the list and select “Background apps.” You’ll see a list of apps that have permission to run in the background with an “On/Off” toggle. The default setting for each app is “On,” allowing each app to run in the background if it likes. Set any apps you don’t want to run in the background to “Off.”

I think I fixed it or at least made it it usable.  I made two changes.  I removed a old firewire card that I forgot about.  It shouldn't have been active but you never know.  And I disabled speed step.  Thanks rsinger and wookie

Also, if you actually are running SONAR at this late date, give the latest version of Cakewalk by BandLab a spin. The audio engine has had some nice optimization performed on it in the 2 years since BandLab's been in charge of it.

I concur - you can install Cakewalk by Bandlab right alongside your existing Sonar install, without issue - most of us that have Sonar keep it, because that allows any of the bundled plugins that came with Platinum to also work in Cakewalk by Bandlab.  You just create a Bandlab account, download and install the Bandlab Assistant, launch it, click on Apps, then install Cakewalk from there, and in a 2nd install, add in the Studio Instruments, if they weren't already present by your having Sonar installed.

Out of the blue (where did that phrase come from?) my old Win 7 computer was crashing, continuously. 
 

I solved the problem. It was throttling, so I was running a computer at half horsepower. I saved my power settings as a custom setting based on high performance, so I didn’t think that was the problem, but it was. So I changed it to high performance and that fixed it. I was running for years with the custom setting so who knows what happened, but it did when one of the last 2 updates was installed. Anyway, all is good again.
