a few minutes or so. Report the latency for each.

LatencyMon will never stop, unless you tell it to.
 
It is a real time monitor, and you just need to let it run for a few minutes, then stop it and review the findings.
 
Sorry I had not made that clear.  DPC Latency Checker would work the same way - it just needs to run for a few minutes.

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.

OK - this is progress.
 
Your computer is having issues streaming audio, so if that gets fixed, your Sonar issues may be resolved.
 
It looks like you have AVG antivirus software running, and this may well cause latency issues.
 
Please try temporarily suspending AVG, just long enough to run the LatencyMon again for a couple of minutes, and then post back with the results again.
 
I used to use AVG, long ago, and switched to Avast for a couple of reasons.  I am able to leave Avast up and running and it does not seem to bother Sonar at all.
 
So, let's just see what your latency is looking like with AVG turned off.  Don't forget to turn it back on prior to getting back on the forum to post your results of the rerun of LatencyMon.
 
Bob Bone
 
Thanks - 

In addition, 'ndis.sys' seems to have a bunch of posts on the web about causing latency issues for folks.
 
Google the following terms, and take a look at some of the posts: 'ndis.sys latency' (take off the 's)
 
Bob Bone
 
 

Do you have a wi-fi adapter on your system?
 
If so, these can absolutely cause bad latency spikes - not always, but certainly it does happen.  I used to major problems with a laptop I gigged with, running Sonar.  I had to disable the wi-fi adapter prior to running Sonar, or horrific latency would rear its ugly head.
 
If you do have one, I would suggest you also temporarily disable it in Device Manager, then run LatencyMon again, and post the results.  AVG and a wi-fi adapter could certainly be the culprits here for you.
 
I look forward to hearing back from you.
 
Bob Bone
 
 

I would use cpu-z to look at what the processor is doing .... Intel Speed Step and AMD Cool N Quiet in the BIOS!
This has to be turned off ! the processor should sit at : Clock Speed 2.3 GHz always
 
HP Pavilion g6 Notebook PC, Hewlett-Packard, 1695 ..goto your systems home page/support and post it here .
Then we can read and advise you as to what drivers you might need to update.

Without AVG
 
PS.  How do you turn off the Wifi adapter

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):   8127.766798
Average measured interrupt to process latency (µs):   4.790668

Highest measured interrupt to DPC latency (µs):       150.819938
Average measured interrupt to DPC latency (µs):       1.759445

 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.
