    Audio appears and disappears randomly


    Hi all,

    For no apparent reason audio from my laptop's internal speakers appears and disappears. As I was troubleshooting I noticed random fluctuation in the audio levels in Windows Stereo Mixer.

    Take a look at this short video here demonstrating both the audio loss as well as the audio level spasms.

    If I cast to an external device like a bluetooth soundbar, this does not happen. This suggests it's a laptop hardware issue but I would like to eliminate any other possibilities before buying parts/taking things. Plus, what's up with the sound mixer? That makes me think it's a software issue.

    And as much as I know how I disabled/enabled audio devices, uninstalled drivers, installed different versions of drivers, etc etc.

    Thanks in advance.

    Seeing as you have performed disabling, enabling, and uninstalling of drivers etc, have you . . .

    [1] Run WU for drivers to see if that corrects it?
    [2] Open an elevated cmd prompt and type in the following cmd and press <ENTER> . . .

    Code:
    sfc /scannow

    I hope this helps!

    I suggest the following straightforward way:

    Right-click on the Start button -->Windows PowerShell (Admin).
    Run this command: sfc /scannow
