Intermittent or quiet sound from HP Envy

[al_sweets]

Bought this laptop new a month ago and having sound problems. Sometimes sound is unusually quiet when at full volume but then will suddenly burst into full volume after a few minutes of playing something.

Other times, sound is louder out of one speaker than the other, but then will correct itself after a few moments of playing something.

Sometimes when you unmute (F5) it plays loudly, but then will drop quietly again. Something isn't right.

Windows is up-to-date and all drivers are updated. Really disappointed.

Your machine has Intel Gen 10 processor. Please perform a clean install Audio software/driver, this should help.

   (a) Download the following driver and save on your computer,
              https://ftp.hp.com/pub/softpaq/sp112001-112500/sp112100.exe

   (b) Go to Device Manager, Sound to uninstall sound driver (Realtek) and reboot,
   (c) Right click downloaded file and select Run as administrator,
   (d) Reboot again.

Regards.

Thanks I will try this.

Can you explain why this is required? Is it related to having a gen 10 processor?

That is new software/driver for Gen 10 processors. Above steps to make sure we do a CLEAN install.

I have exact same problem, but with 8 gen intel processor. Please help, I already tried reinstalling drivers without luck.

@Banhien, I am still experiencing the same issues. Sound levels are dropping and rising themselves. 

It's worth noting though, when I uninstalled the Realtek driver, and then rebooted, it re-appeared when I went into Device Manager as if it auto-installs on reboot. But I installed the download anyway. Not sure if there is another way to avoid this automatically re-installing on reboot?
