New HP ENVY 17-CH0005NC and high pitched sound from speakers (need advice and help from HP)

[KT_Customs]

Hi,

I'm actually having problems with notebook audio on brand new notebook HP Envy 17-CH0005NC. (HP ENVY-17CH00xxx).

We have in our company threee notebooks and all of them making high pitched sound from internal speakers, when some sound is played or music. It is very annoying and can be heard in quiet room in low volume of played media. When I stop the music or media.. it can be heard for 8-10 seconds and then the high pitched noise is gone.

I have tried ...

1. Clean install Windows 10 - Nothing
2. Reinstall audio driver - Nothing
3. BIOS version flashed from old F4 to F10 version - Nothing
4. The quiet high pitched sound is here even on battery/adapter
5. Even, when all drivers are installed properly, the quiet high pitched sound is comming from speakers, when some audio/music starts to play.

This is for me a big issue, Can somebody from HP make a test and let me know? I think that there is affected all HP ENVY 17-CH00xxxx version. Could somebody test this and report it here,? Because when this will not be solved or there will not be any statement from HP, I will return all laptops and request money back from our retailer, because this annoying issue.

Thank you all.

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/sp112495.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.

I have performed all the steps provided by you, but this not helped. There is still high pitched noise on all three laptops event after clean install of Audio driver.

Hello,

I need to escalate the problem directly to HP, to make them check the issue... This is not normal on three new laptops, with original OS or clean install and all new drivers installed from HP. This need to be solved by some patch, or BIOS update that eliminate the problem.

Thank you.
