Now using Windows 10 on an HP 4540s laptop. Audio/speaker control button has a red X. Cannot unmute or adjust audio. There is no audio.

HP Laptops Shipped with Hidden Keylogger

Michael Myng, more commonly known as ZwClose, was approached by a friend to look into the possibility of controlling the keyboard's backlighting on his HP laptop. Michael was down for the challenge, and his friend sent the Synaptics SynTP.sys file over to him. After analyzing the keyboard driver, he found the sleeping keylogger. The logging function is disabled by default. However, intruders can enable it easily by modifying the registry value through malicious code. Michael reported the issue to HP, and the company released a list of the affected laptop models along with a security patch. The list contains over 400 models from HP's most popular product lines like the EliteBook, ProBook, ZBook, Spectre Pro, ENVY, Pavilion, OMEN - just mention a few. Now that the vulnerability is public, we urge HP laptop owners to install the security patch ASAP. The fix is also available on Windows Update if that's your preferred method.

HP Audio Switch

My PC is an HP AIO desktop using Windows 10 version 1809, the HP Audio Switch came already installed and it all works fine.
HP Support Assistant has now listed an Audio Switch update which I have not yet installed.
I have surfed the web trying to find out what this switch actually does. It appears to control speakers between apps.

I only have my one computer and no other apps. Thus there is only the one set of PC speakers involved.
In my case this switch seems redundant and I am considering leaving it alone and not installing the new update.

The last thing I need is for my audio/sound to fail.
So briefly -
1. Is the HP Audio Switch essential for my audio/sound ? No switch - no sound ?
2. If it is not, then I will ignore the matter and not install the update. Leave well alone.
3. If it is, then I will install the update.

Your comments please would be gratefully received.

Nobody replied to this issue, so here is my conclusion.

Malwarebytes AdwCleaner listed the HP Audio Switch as pre-installed unnecessary crap and wanted to delete it.
I have not deleted it as it is doing no harm, albeit also doing no good. Let sleeping dogs lay.

So that answers and concludes my problem.
