No sound op HP ENVY 15-ep0171nd laptop after update to win 11

[nico1750]

Hello

After update to win 11  64 the sound seems unconnected on B&O speakers.

I run all updates and tests without result.

What I found sofar :

1. Intel Smart Sound Technologie OED is switched off. (The yellow triangel)

I try the uninstall and restart without succes

2. In sound and games, the NVIDIA High Defenition Audio drivers are updated, done with HP and Intell

Update drivers did not solve the problem

3, The sound icon on windows screen is not working, There is no audiodevice installed/

4. B7O can not connect wirh RPS service.

5. HP Audioswitch gives 3 NVIDIA output, not connected

6 HP Audio playtest gives Device not found.

How can I reinstall the sound which seems to have been broken with update to win 11?

Thanks in advance

Noco

Hello Ub6424

Man you are my hero. (-:

It works and I have my sound system back.

For anyone who need the solution:

Keep your external power and internet connected and disable your antivirus software (and bitLocker X11 pro)

Take your time there is a lot of writing to the bios.

Many thanks

Nico
