Notebook Audio

I believe a Windows update over the weekend is now crashing my audio service. It was working fine for the few weeks I had the laptop, then stopped working this week. Now the speaker has an X through it and says No Audio Device is Installed. I have no sound regardless of device - internal speakers, monitor speakers, bluetooth headsets or wired USB headset. I need updated drivers or another fix from HP

I am using the latest Realtek drivers from HP, version 6.0.9556.1 rev D dated 9/11/23

Removing the Realtek Audio Device and using earlier drivers does not work

I have refreshed Windows 3 times, twice from the local partition, once downloading Windows from Microsoft

The Windows Audio Service (set to Automatic) will not start. It briefly starts and the speaker icon returns, then the service crashes within a second and sound goes away again. Event viewer shows the service crashing, then restarting in a constant loop. The Audio service is set to use a Local Service account. Changing this to Local System does not fix the sound. I can't change the logon back to Local Service, hence the multiple Windows refreshes

Event viewer shows the application behind the Audio service crashing:
