Has anyone seen this problem and could they help me fix it? I am using LatencyMon to see what is happening. Our system seems to have trouble handling real-time audio and other things. You will probably get buffer underruns that show up as dropouts, clicks or pops. One or more DPC routines from a driver running on your system are taking too long. Maybe one issue comes from power management; you can disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates. Here is some of my system info: OS version is Windows 11, but it says the actual number is 10.0 version 2009 build 26100 (x64). Hardware is an OMEN by HP 40L Gaming Desktop GT21-1xxx and the BIOS is F.18. The CPU is an AMD Ryzen 7 7700 with 8 cores for logical processors, using 16 processor groups each with a size of 16. I have about 15 GB of RAM total. Let me know if you can give me anything else or help, thanks!

Here is the rest of the details CPU SPEED _________________________________________________________________________________________________________ Reported CPU speed (WMI): 3801 MHz Reported CPU speed (registry): 3793 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): 4582.60 Average measured interrupt to process latency (µs): 14.422074 Highest measured interrupt to DPC latency (µs): 4576.60 Average measured interrupt to DPC latency (µs): 7.686155 _________________________________________________________________________________________________________ REPORTED ISRs _________________________________________________________________________________________________________ Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.
