Acer Aspire Nitro VN7-592G Audio randomly pops and cracks

The speakers randomly give a pop sound (like tuck) while say when I'm browsing facebook and while scrolling I see a video which auto-plays (Even though without Audio). I also hear it randomly at other times whose pattern I have not been able to identify but sometimes before playing an audio and after stopping it.

The audio itself is fine. I can't 'disable enhancements' because I am left with only turning on or off Dolby Audio. I don't see how to update the Dolby Audio within the program itself as it just shows this:Capture.PNG

 

I then tried updating the Realtek SST driver through device manager and it detected a better one however after quite some time of downloading and installing where it felt it was stuck/frozen, I was displayed a message along the lines of a better driver was found but encountered an error while installing.

Rolling back did not work so I uninstalled and restarted. Now it says that the best driver is already installed. I assume the latest one has been installed.

 

Realtek High Definition Audio (SST) 6.0.1.7801 4/19/2016

 

There's another Intel Smart Sound Technology, Display Audio and NVidia Virtual Audio Device. All up-to-date.

The audio occasionally fixes itself so I kept running the Latency test until it detected again. The popping didn't happen so it didn't reach red as frequently as when it did before but the program did say that there could be issues in playing real time audio etc.

I ran a DPC Latency and here's the report

Note: My laptop is just a month old which was a display piece at Carrefour prior to me buying.

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.

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.

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.

    Same here. I experience this issue since I bought this laptop.

    Please let me know if anybody has a solution to this. My speaker popping has returned back.

    I hope the administrator can bring this to the attention of any Acer technician online asap. Man MadMan Sad

  • benjaminchoatebenjaminchoate Posts: 2Member

    I was experiencing similar audio popping and it seems like roughly the same time frame. Mine, however, has been resolved somehow now, and I think it may have been the Win10 Anniversary update that did the trick (I got mine early through the Windows Insider Program), though I also performed a windows refresh recently and it could have been that.

     

    It's not a for-sure solution as I'm presenting it, but if you're still experiencing the pops it might be worth trying.

     

    Cheers

     

    Edit: I nearly forgot: I also updated the BIOS from either 1.03 or 1.06 to 1.11 around the same time.

    I have also updated my BIOS, reinstalled, Rolled back drivers and done all the general troubleshooting steps.

    Other than Thunderbolt Update issue (which is a story for another thread) and another one.

    I hope Acer development team can look into this before this model gets too old, or it already is, perhaps? Smiley Sad

    Also to add, apart from the crackling. My left speaker randomly decides to switch off. I confirmed with stereo tests that only the right one works.

    So I can conclude from a lot of observation that

     

    1. It is only the left speaker that crackles
    2. It is only the left speaker that occasionally finds itself shut off.
    3. Headphones don't have any issues.


    I really want to claim on my warranty but they format my laptop which I want to avoid!

    Hi Shumayal,

    Can you check my latest post here: http://community.acer.com/t5/V-and-VN-Series-Laptops/Aspire-VN7-792G-strange-sound/m-p/480187#M14550 and tell me if your problem is the same?

    @Otoshigami No, I don't get those ticks often. I only get it occasionally while watching videos but since they seem to occur at the same place on the video,  I deduce that it is normal for me.

    Anyhow, to update anybody else following my thread. I would like to say that my problem has been resolved. I don't hear anymore crackling.

    I sent my laptop to my local Acer approved service center and Acer ME connected with their technicians personally to advise on my problem as we had already done the troubleshooting via email.

    The service center ordered new speaker and replaced my left speaker which was the faulty one.

    My left speaker would not work occasionally. And when it would work, it would crackle. Now that is fixed.

    The latency results are also lowered from before but still high. But hey, if I don't hear observe any audio problems or performance issues, then it does not matter to me. I would appreciate if someone more competent would look into these results and convey them to the right channels for driver development and hope to see driver updates soon, if relevant.

    Thanks Acer for this platform and the wonderful customer service in my region Smiley Happy. I think people should really stop troubleshooting themselves above and beyond what's reasonable and let experts do the job for once.
