Freezing in Asio Guard

Cubase
1

Hi all,
When I use asio-guard, every time I add an instrument or change tracks in my template, my audio, meters, and all functionality, stops for a few seconds. That might not seem like a big deal but when speeding through a project, it definitely slows me down and “takes me out” a little mentally and creatively. Obviously something is causing this. It used to happen with 10, stopped in 11 and recently started again in 12. Any ideas on why?
Thanks

Hi Fredco
I would first run Latency mon too find out what other processes could be runnig in the background to cause the issue , What is your graphics card, is it on Max Performance ,have you setup up a power plan , have you optimised the computer for audio work ?

Thanks,
I actually don’t know how to read these Latmon reports but it seems as the most hard faults are coming from Microsoft Defender.

It tells you on the website how to …
Page faults don’t really matter , it’s the US latency interupts in the 4 bar graphs you need to pay attention to , the higher they go will be the highest latency process your computer is preforming which can interrupt the audio process , so any thing under 1000us is just about workable , under 500 will be stable , under 200 will be really good and under 100us will be absolutely great , if you can get as low as my current system then you are at the best it can perform

This is what I got

CONCLUSION

Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:27:05 (h:mm:ss) on all processors.

SYSTEM INFORMATION

Computer name: PROSTUDIO
OS version: Windows 11, 10.0, version 2009, build: 22621 (x64)
Hardware: Z690 UD AX DDR4, Gigabyte Technology Co., Ltd.
BIOS: F7b
CPU: GenuineIntel 12th Gen Intel(R) Core™ i9-12900KS
Logical processors: 24
Processor groups: 1
Processor group size: 24
RAM: 130942 MB total

CPU SPEED

Reported CPU speed (WMI): 340 MHz
Reported CPU speed (registry): 3418 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.

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): 4038.70
Average measured interrupt to process latency (µs): 7.272478

Highest measured interrupt to DPC latency (µs): 336.70
Average measured interrupt to DPC latency (µs): 3.940451

REPORTED ISRs

Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Highest ISR routine execution time (µs): 144.869514
Driver with highest ISR routine execution time: portcls.sys - Port Class (Class Driver for Port/Miniport Devices), Microsoft Corporation

Highest reported total ISR routine time (%): 0.002496
Driver with highest ISR total time: portcls.sys - Port Class (Class Driver for Port/Miniport Devices), Microsoft Corporation

Total time spent in ISRs (%) 0.003918

ISR count (execution time <250 µs): 1000613
ISR count (execution time 250-500 µs): 0

ISR count (execution time 1000-2000 µs): 0
ISR count (execution time 2000-4000 µs): 0
ISR count (execution time >=4000 µs): 0

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.

Highest DPC routine execution time (µs): 554.192218
Driver with highest DPC routine execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation

DPC count (execution time 1000-2000 µs): 0
DPC count (execution time 2000-4000 µs): 0
DPC count (execution time >=4000 µs): 0

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: chrome.exe

Total number of hard pagefaults 1971
Hard pagefault count of hardest hit process: 946
Number of processes hit: 37

Ok so you need to find the device that’s using the mini port driver and either update it or disable it to test

Haha. I have no idea what any of that means.

If you look in the processes section , it lists the processes accessing the system and the highest latency process will be at the top which should tell you which driver process it’s conneted with

I see where I need to look now. Thank you! I’ll try to find it

12

I notice you have Nvidia graphics , are you running the studio version driver with only the driver installed , NO Experience ? If you have the full bloatware installed that could be your issue

13

Again , I have no idea but I will check into that. I really appreciate your help.

14

The machine was built for me by Jim at purrrfect audio. He’s built a few for me but this is the newest and the only one I’ve ever had trouble with. All the others have been rock solid.

15

No worries .
I know there were issues with 12/13th gen cores but maybe someone will chime in if removing the Nvidia bloatware doesn’t work but the second highest latency report was your graphics so my bet is …
Hope you get it sorted

16

Thank you very much
