    Hello,

    first up, some details to my pc;
    running win 10 64bit
    980 Ti Sc
    16GB RAM
    MSI Z170M Mortar Mainboard
    i7 6700k CPU

    For audio hardware;
    using a 2.1 stereo system
    and a Razor KaveXTD 5.1 headset/mic


    Since quite some time, I have had an issue with the audio on my PC. At first, I thought it was an issue with my fairly new headset, that's why I contacted the manufacturer for support, but they couldn't help me any further even after explaining every detail and doing adjustment to my audio settings in windows as well as the headset's software. Just today it came to my mind that the issue actually might not even be with the headset. Since I started hearing it through my 2.1 Stereo as well now. Because before I was only able to hear it through my 5.1 headset, since it has much better audio quality.

    For some clarification, this issue ONLY happens when I play video games. It NEVER happens when I listen to music or watch videos.

    Firstly I recorded an off-screen video with my phone, holding the mic of it into the headset to capture the audio issue. Today I captured a gameplay video with a recording software, thinking that if the issue actually is NOT with the headset, I should be able to hear it even in the captured video, and I did.

    The issue is that the audio sounds crackling, or as if you'd listen to a CD in a CD player, and the CD had a scratch or so, and it skips audio. This does not happen constantly, I can play fine for an hour or 30 minutes, then the issues appear and stays there for 30 minutes, and disappears again. After that, it might come back after an hour or two, but maybe only for a few minutes, and disappears again. Sometimes the issue is really strong and intense, other times it is more subtle.
    It is really strange and sporadic.

    Also, I doubt the issue is with the PC soundcard since the headset has its own soundcard. And since I hear the issue though both, my stereo and the headset, It would literally have to be an issue with both then.

    I will link the video here underneath to whoever wants to hear can do so. The video starts off with a short off-screen clip, you can hear my buddy talk, even his voice is affected by the issue. We talk through a software called Discord. But Discord is not the issue, I have already closed the software while the audio issue was happening, went back into the game, and it was still present. So Discord is not the issue. The second clip is the in-game video captured with Nvidia Experience, it is more subtle in that case, but still noticeable.

    I have no clue how to fix this or what it could be. So if anyone has an idea, I would be very thankful. Because it really bothers me. Especially after having bought such an expensive headset, and not being able to enjoy it.
    Thanks.

    You can use LatencyMon (http://www.resplendence.com/latencymon) to spy after your rig, and may be it would help to see a culprit (for example some driver).
    Are you sure your OS (and hardware) is not overwhelmed with mega amount of processes (like browser with 1K tabs), or a heavy ones?

    Hi!

    I am not sure if I am supposed to run this software while the issue occurs, or just run it in general? Anyway, I ran the software and took some screenshots.
    I use MSI live update 6 to check my drivers, and all my drivers are up to date.
    Usually i close all programs while gaming, occasionally Chrome is open, but never more than 4 tabs. I took screenshots for that as well.

    Keep the program running as long as it needs for the stutters to appear, if they happen then LatencyMon can tell you without a doubt whats causing it.

    LatencyMon can copy its report into Clipboard so you can paste it here as a text.

    Alright, thanks! I will report back once I have had the chance go get results. Since the issue is so sporadic, and I don't always have time for extensive testing. But I will get to it as soon as possible.

    Okay, I have let the program run for several hours now. And it reported an issue. Although I didn't really notice the issue as usually. (Probably because I have been playing with my 2.1 stereo where I don't hear the audio break- ups as well as with the headset.)

    I will paste the results here.

    CONCLUSION
    _________________________________________________________________________________________________________
    Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. 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 3:10:59 (h:mm:ss) on all processors.

    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.

    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.

    I see no criminal there. ISR times are good, DPC times are less good but still normal. 50 ms for a hard page fault resolution is normal too.

    Hi NorthFront, had a similar issue on my board and after much trial and error, disabled Realtek through device manager. I wasn't using it but it caused no end of dropouts, click, pops, etc. High memory usage was also a symptom of the problem. Now use Nvidia HD audio driver (default) and all is good...
    ..let us know if that helped..

    Sorry for the late reply. I was actually trying to get proper results this time. Because last time the issue didn't occur, but since the software reported that my system is not ready for real time audio, I thought that would be enough regardless.
    I was playing for two hours and the audio problem started big time. I have another report copied if that might help and someone may look through it? In case that could help narrow the issue down.
    Regardless I will try to uninstall/deactivate Realtek HD audio drivers. Thanks!

    And again I see no bad data in report. May be problems are not in OS kernel where LatencyMon collects its data.

    Well, I uninstalled Realtek, but the problem still persists.

    My two cents.
    Disable the Realtek on-board audio, in the BIOS and install a Creative Labs Sound Blaster Z sound card.

    Assuming you connect the headset to four 3.5mm (1/8") mini-jacks on the Realtek on-board audio (green, orange, black, pink).
    How do you have the 2.1 speakers connected to the PC?

    Aren't Razor KaveXTD 5.1 headset/mic USB headsets? They don't bypass your soundcard right? Then it shouldn't have anything to do with soundcard.

    Can you test sound while watching 4k videos on Youtube? I am wondering if issue happens as GPU 3D clocks kicking in or CPU starts to heat up.

    As already might been mentioned, disable on-board sound on BIOS and make sure Nvidia doesn't affect your sound. (remove nvidia HDMI audio driver to be save)

    Hello!
    So, I have disabled the onboard audio in the BIOS, which only left me with my headset as a capable audio source, but the problem was still continuing to be an issue, unfortunately.
    My headset is plugged in via USB only, in the back of my PC. And my 2.1 Stereo is connected via 3.5mm audio jack also in the back of my PC.

    I did watch a 6min 4K video on youtube in fullscreen. My sound was fine. CPU was around 50-60°C and GPU around 50°C.

    Interesting. Maybe we could narrow down the problem.

    Have you tried to run games in window mode? "alt+enter" should work to switch mode.
    Does running CPU or GPU benchmark also cause sound to crack? (listen to music while running Prime95 / FurMark)

    Hello, yes the problem does also exist in windowed mode.
    I have also tried FurMark, both in 1080p and 4k, with and without AA.
    No sound issues there.

    I have just gotten to to test the game.

    The problem is because its a Creative product. JK JK I think.........Try different driver revisions and see if that stops the crackling. Use the onboard audio temporarily and see if you get crackle. If not, then its the SB card / drivers. gl
