Schenker Vision 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: svchost. Total number of hard pagefaults Number of processes hit: CPU 0 Interrupt cycle time s : CPU 1 Interrupt cycle time s : 5.

Posted 09 May - PM Ok,that helped.. What happens when you take the external drives out? Is pc home built.. And the obvious or maybe not.. Posted 10 May - AM Ok,that helped.. Posted 10 May - AM Ok,.. Will do. Thank you so far by the way! You're probably the most helpful person I've encountered while trying to solve this. Anyways, memtest has been running for the past 10 hours, and it's only on pass Looks like I'm gonna be here a while.. Posted 10 May - PM I also performed windows memory diagnostic, nothing was found.
Posted 10 May - PM Ooo, alright! Reply to quoted posts Clear. It can even be a wireless keyboard. If its your mother boards chip set you probably screwed but you can try disabling each USB hub etc in your operating system but search your chipset on the web under audio pops and crackles and you will quickly find out if its a big offenderthe bad news is most chipsets except a few are going to cause some type of problem If you know any daw builder they know this topic like the back of their hands--they know what to use and the boatload of components to avoid.
My Studio. In Windows 7 64 it's about I downloaded the latency checker and it checked all the latencies which are most definitely there for the checking. Now I'm looking for a solution. I'm reasonably sure that the issue I'm having is with my wireless card, but I want to be sure before taking any action, so I tried downloading that process monitor in StereoPari's post. Could someone please tell me what I should be looking for with the process monitor? There's a filter on it but I don't really know what I should be filtering and what is useful information.
I noticed my DPC latency was spiking to around microseconds on mouse usage. Normal idle being around 10 microseconds with all non-essential stuff shut down. Jacking the mouse directly into a USB port instead of into the USB hub cut those spikes down to 50 microseconds, much better. Might be worth checking that out if you are having DPC latency problems.
Good advice. After disabling what I don't need it's never let me down. Quality and priority for audio definitely differs from manufacturer to manufacturer but it's entirely possible to get a great audio machine without much tweaking. Ok I'll have a go - and I'm sure someone will jump in to correct if I get any details wrong And it hasn't got anything to do with background processes - it's about device drivers - it's a software problem.
Deferred Procedure Calls are basically a mechanism with which Windows handles interrupt servicing. As you might know interrupts are a mechanism with which devices can proactively signal they need attention from the processor - e.
Hundreds or thousands of interrupts are occuring every second within a PC. Windows needs to manage and prioritise these - critical interrupts might be handled in full immediately, whereas lower priority requests will be queued - and this is where DPCs come in.
Windows will acknlowledge the interrupt and queue it - and come back to actually do something about it later. An interrupt from an audio interface to say there is some audio data available isn't considered critical.
The driver uses the DPC mechanism in Windows along with most other devices. So even if the audio interface needs data for its buffer for output or has data avaialble in its buffer for input the actual audio driver code that will move this data isn't actually invoked till Windows gets round to processing the relevant DPC item on the queue. This is where problems can occur. Windows will process other things ahead in the queue before servicing the audio request.
If other drivers are badly implemented they can use too much processing time delaying processing of our audio request our audio driver can also use too much time. Clearly as audio is time critical if there is too much of a delay before data transfer occurs the audio buffer may empty output or overflow input - therefore audible pops and clicks occur. Obviously this is why having a bigger buffer helps.
Obviously we want a low as possible value which indicates all the drivers are well written and efficient - the lower the value the less likelihood that they'll prevent timely audio data transfer and the better chance of being able to use smaller buffer sizes for lower latency without pops and clicks.
I had a bad experience with DELL laptop. DPC latency issue drove me nuts. Latency is lower than before and drop out problem is gone. But I still think PC really is not made for streaming audio. My Dell laptop works fine. But it needed an external sound card to make it so.
I use a Presonus AudioBox. Patently UN True. I understand but you never know if your next PC will act that way. PC is designed to work with many different hardwares and different tasks which means it is not the machine dedicated for audio streaming. Standard PC maker will never design their PC just for audio since there aren't that many audio users compare to the rest of users.
If I experience one drop out in year, I'd consider it is not so stable and not really dependable. Unless it has super performance I'd think it's a toy. But this is just me. Look for ways to get rid of bloatware?
Thats what ive been told to do in a situation like this.
