hi, recently got my new 6900 XT card and it seem to have very hige DPC latency spikes randomly and when it happend i hear a crackle in the sound. I have update every driver, both BIOS and GPU driver(made sure to use DDU to before installing GPU driver) I also made sure to turn off most of the power saving features in the power plan.
here is the report i get from Latency monitor.
_________________________________________________________________________________________________________ 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 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. LatencyMon has been analyzing your system for 0:08:33 (h:mm:ss) on all processors. _________________________________________________________________________________________________________ SYSTEM INFORMATION _________________________________________________________________________________________________________ Computer name: DESKTOP-VCNGV6S OS version: Windows 10, 10.0, version 2009, build: 19042 (x64) Hardware: System Product Name, ASUS CPU: AuthenticAMD AMD Ryzen 9 3900X 12-Core Processor Logical processors: 24 Processor groups: 1 RAM: 32681 MB total _________________________________________________________________________________________________________ CPU SPEED _________________________________________________________________________________________________________ Reported CPU speed: 380 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): 18237.40 Average measured interrupt to process latency (µs): 5.910152 Highest measured interrupt to DPC latency (µs): 18234.0 Average measured interrupt to DPC latency (µs): 2.446007 _________________________________________________________________________________________________________ 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): 5.640 Driver with highest ISR routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation Highest reported total ISR routine time (%): 0.000066 Driver with highest ISR total time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation Total time spent in ISRs (%) 0.000066 ISR count (execution time <250 µs): 10582 ISR count (execution time 250-500 µs): 0 ISR count (execution time 500-1000 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.

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.

Has anyone encountered this?
Hello,
same issue here, i created a ticket some weeks ago but had no response, the only way to get the latency back to normal is to go back to the old 2015 defaut ethernet driver or not to use the intergrated ethernet ports of the motherboard, can you try?
Having the exact same issue and even the same values, 27ms spikes on the dxgkrnl.sys driver, not using my second screen solves the issue, sometimes borderless screen also fixes it. I've performed several Bug reports and post and its 99% a driver issue. Lets hope AMD can fix this one.
