Windows 10: High lattency and cracking sound when playing real-time audio and video and CPU is slow

Hi


I have a freshly build PC with the following configuration: First pic bellow

I have had troubles with some blue screen of death errors these days second picture bellow WhoCrashed

Then I updated my drivers and the errors reduced but i still have cracking sound and video and audio out of sync when playing live videos Youtube.


Then I ran LatencyMon and the results were:


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. 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 0:05:22 h:mm:ss on all processors.

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.



WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

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: 20613.10

Average measured interrupt to process latency µs: 10.653466



Highest measured interrupt to DPC latency µs: 20607.40

Average measured interrupt to DPC latency µs: 6.332420





_________________________________________________________________________________________________________

REPORTED ISRs

_________________________________________________________________________________________________________

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

_________________________________________________________________________________________________________

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.

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: perfwatson2.exe



Total number of hard pagefaults 27194

Hard pagefault count of hardest hit process: 18795

Number of processes hit: 21

No sound while playing audio and video files.

Hi,

I appreciate if you could answer to a few questions to narrow down to the issue.

• Which is the application that you are using to play the files?
• Did you try the same on a different player?
• Did you perform any troubleshooting steps?

As an initial troubleshooting step, I suggest you to check if the volume is set low or in mute state in Volume Mixer.

• Right click on sound icon.
• Open Volume Mixer check for the application that you are playing the files with and increase the volume and check.

If the issue still persists, I would suggest you to run “Playing audio” troubleshooter to diagnose and fix the issue.

Follow these Steps to run Playing Audio Troubleshooter in Windows 10.

1. Type troubleshooting in the search bar.

2. Select Troubleshooting.

3. Select View all on the top left corner.

4. Click on Playing audio.

Also refer: http://windows.microsoft.com/en-us/windows-10/fix-sound-problems#v1h=tab01

Hope the information helps in resolving the issue related to the sound issue. Let us know if you need further assistance. We will be happy to help.

Thank you.

 

Distorted Sound

Hi Zaki,

Distorted sound can be be produces if there is an issue with the hardware or software. Please answer the following questions for us to narrow down this concern:

• Is it affecting all music, videos, and online videos?
• Which sound card is set to default? Realtek High Definition Audio or High Definition Audio Device? You will know it by typing
  "sound" on the search box and select Sound, under Playback, the default speaker should have a check.

Please run Playing Audio Troubleshooter by following these steps:

• Type "troubleshooting" on the search box.
• Select Troubleshooting on the result.
• Click View all.
• Choose Playing Audio and follow the steps.

Looking forward to your reply.

 

N8: high definition video slowed when played on PC

Yesterday I shot a 1,5 min film in high definition with my N8 and that's the odd: when played by the N8 player itself it's absolutely ok, when played by (after uploading to) my desktop's WMP, well has a correct audio but a slower than real video, so the
audio and the video soon become out of synch and the audio ends , of course, some seconds before the video.

Any idea?
