HP ProBook 455 G9 AMD no sound

[mrstrong]

has anyone seen (or heard (not)  ) of anything like this: 

audio works for a bit then just stops, troubleshooter can't solve.

uninstalled and deleted drivers then reinstalled latest from HP, worked for a bit then stopped again.

weirdly on boot you sometimes get the windows boot up sound but it cuts off

before it's finished playing

Is that RealTek audio?

[mrstrong]

yep, says Realtek 6.0.9764.1

Any chance it's the antivirus interfering? Is this on a fresh build? Does it do it in Windows 11?

“Sometimes” HP doesn’t always provide the right 3rd party driver. 
I would try a previous version of the driver and also try downloading from Realtek. On rare occasions I’ve even unpacked and used a driver for the exact same component from a competitor such as Lenovo and that has worked.  Have you checked the hardware device code in System Information / components that it really is Realtek?  Occasionally, even in a continuous run of serial numbers there is a random differently branded component.
