    Sound stops, but comes back after a sound problems "quick scan"


    I've suddenly started getting a very annoying problem: I get no sound from my speakers. In Sound Settings, the output device is correctly set, and in the Volume Mixer all devices/applications are set to maximum volume, as is the speaker icon in the system tray.

    If I elect to "Troubleshoot sound problems", the app does a "quick scan" and plays a tone which I hear. After that, the sound works normally again, until the next time.

    What is happening? Why does the sound go out and why does a "quick scan", which seems to have made no changes that I can determine, cause the sound to work again?

    Hi, right at the end of running the troubleshooter there's an option at the bottom something like
    View detailed report
    which will give you something like this:

    Look for something that's been fixed- you may be lucky.
    After that, you have to try to find out what caused that- which might be a process of elimination, e.g. starting from a clean boot.

    When sound dies, go here and check the level indicator (green bars) and try the Test option.

    Thanks for the reply and suggestions. I've since found out that putting the computer into Standby and then waking it up again is one cause of the problem. (There may be others.) Here's a summary of the problem:

    The System sound (beep) still works. For example, sliding the volume slider causes a beep at the end.
    The following do NOT work:

    • Playing music from Amazon Music (over the internet)
    • Playing a Youtube video
    • Playing music using VLC media player (from a local mp3 file)
    • Using Zoom
    • Playing a "beep" using the macro utility Macro Express

    Attach 1 shows all output devices with sound

    Attach 2 is the Windows "Get Help" window
    I clicked "Yes" to "Did you hear the sound (beep) that just played?"
    At this point everything works again. Nevertheless, I continued where it says it couldn't find the issue and wants me to reproduce the issue during a second scan. I played something, but of course it didn't reproduce the issue since the issue goes away after the first beep.

    Attach 3 is the window after the failed second attempt.
    I chose "Yes" to the question about sending a diagnostic report.

    Attach 4 is the next window.
    It shows that "File0.zip" is attached but there's no way to open it and it doesn't say where it's located. I can't find the "Troubleshooting report" you show in your reply.

    Attach 5 is the "Sound" window. It is unchanged by the Troubleshooting step. (Note my speakers are connected to the front panel which Windows shows with a headphone icon. I've had them connected this way for almost a year with no problems.) When I click Properties > Advanced > Test there is no sound until I run the Troubleshooter. Afterwards it plays correctly.

    Hi, I've not seen that troubleshooter before- interesting- the Get Help link can often be pretty useless so I tend to ignore it.

    The built-in one most people use can be started from Settings or by rt clicking the volume icon, click Troubleshoot... and you can progress to the Window I showed. Also from the Control Panel:

    What we're looking for is what was fixed. Hope it still exists in 20H2.

    Your speakers are effectively wired, so no USB or wireless issues.

    When the problem recurs, you can try the last part of my previous post, and note the state of the output device.

    It could be something running is responsible - depending on how often this occurs you could try elimination- e.g. does it happen after a clean boot...

    File0.zip I guess will be some sort of log or perhaps simply details of your hardware and software to support the report.
    You could try using a 3rd party fast search tool such as Locate32 (which I like) - free- to find this, but I'm guessing its content won't be of interest assuming it's interpretable.

    After more experimentation, I conclude:
    The problem always (and I think only) happens after coming out of sleep/standby.
    The problem does not occur after booting up.
    I ran the Control Panel troubleshooting app. It found "Issue not present" for all potential issues. (Nor did it fix the problem.)
    I ran Settings > Manage sound devices > Test and got no sound, but neither any indication that it found anything wrong.
    In conclusion, the "Troubleshoot sound problems" accessed by right-clicking the speaker icon in the system tray runs a scan that always* fixes the problem, but provides no indication that it's aware that it did fix the problem. Other tests neither fix the problem nor indicate that anything's wrong.

    * (FWIW, if I'm actively streaming something (though with no sound) and run the troubleshooter, it does not fix the problem. Apparently to work the troubleshooter has to be run when there's nothing else also using the speakers.)

    Very odd. You might check this setting, but I have no clear idea what might cause this.

    Suggest checking if the problem exists after a clean boot.
    I've suddenly started
    - have you had any sort of driver or Windows update that might cause this? (Update History) Installed/uninstalled anything?

    - do you have an appropriate System Restore point you could use?

    I finally gave up trying to fix the problem and restored a backup I'd made ~10 days ago. The problem is now gone, though I have no idea why it occurred. Thanks for the suggestions.
