Audio issues with my Legion Y545 Gaming Laptop.

2020-09-19, 17:23 PM

I have been having problems with the audio with my laptop for the longest time, and two days ago after trying to fix it or get it fixed I found latencymon and did a Scan. I have had my speakers replaced, tried to disable Realtek, and more but I will take any assistance if anyone can help.

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. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. 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  23:07:15  (h:mm:ss) on all processors.

CPU SPEED

_________________________________________________________________________________________________________

Reported CPU speed:                                   2592 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):   7870.50

Average measured interrupt to process latency (µs):   4.789709

 

Highest measured interrupt to DPC latency (µs):       7847.10

Average measured interrupt to DPC latency (µs):       1.769759

 

 

_________________________________________________________________________________________________________

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):              3059.303241

Driver with highest ISR routine execution time:       HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation

 

Highest reported total ISR routine time (%):          0.022081

Driver with highest ISR total time:                   HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation

 

Total time spent in ISRs (%)                          0.026810

 

ISR count (execution time <250 µs):                   36249625

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

ISR count (execution time 2000-4000 µs):              70

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):              6960.712963

Driver with highest DPC routine execution time:       ACPI.sys - ACPI Driver for NT, Microsoft Corporation

 

Highest reported total DPC routine time (%):          0.037599

Driver with highest DPC total execution time:         dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

 

Total time spent in DPCs (%)                          0.095881

 

DPC count (execution time <250 µs):                   262808030

DPC count (execution time 250-500 µs):                0

DPC count (execution time 500-10000 µs):              22826

DPC count (execution time 1000-2000 µs):              234

DPC count (execution time 2000-4000 µs):              428

DPC count (execution time >=4000 µs):                 49

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:                 msmpeng.exe

 

Total number of hard pagefaults                       274941

Hard pagefault count of hardest hit process:          60449

Number of processes hit:                              217
