SP7 - No audio after upgrade to Windows 11

[massimo]

Hi all,

after upgrading to W11 i completely lost audio, even the volume keys on the top of the tablet do not work anymore.

I've tried a lot of stuff, i've installed Surface pro 7 drivers package from MS website ( Download Surface Pro 7 Drivers and Firmware from Official Microsoft Download Center ),
i've even restored the OS, but audio do not come back.

I've a yellow warning on driver "Intel OED technology smart sound"

Any idea?
Any help?

thanks

Downloading this might fix…

Intel® Smart Sound Technology (Intel® SST) Driver for Intel® NUC 11 Compute Element

This download record installs the Intel® Smart Sound Technology (Intel® SST) driver for Intel® NUC 11 Compute Element

www.intel.com

the package has an entire stack of driver and it has not a setup.exe
if i try to install them manually the OS give issues on the audio driver says it has no certificate

I know you’ve probably tried EXACTLY this before, but if not …

- Disable and REMOVE drivers for all sound hardware. Then cold reboot.

oh, thanks a lot!
it worked
the SP7 reinstalled Realtek audio driver instead of the Intel one and now audio works again

much thanks!

Apologies for bumping an old thread. I'm having same issues as OP.

Followed sharpuser's suggestion and the sound will work for a minute or so after the reboot. Then reverts back to the Intel drivers and no sound again. I disabled the Audio Controller, hit Uninstall and checked off "Attempt to remove driver from device", and finally rebooted.

Is there anything I'm missing here?

Thanks in advance!

Sorry you are having that trouble, @shuttlenote. What seems to be happening is that Windows thinks the Intel driver is newer, and is a suitable replacement.

Have you tried directly downloading new Realtek drivers? I believe the latest version is R2.82 (2017-07-26).
