Windows 10: Asus Win11 laptop media keys, camera, and speakers stopped working suddenly

Hi there,I have a cluster of problems that have occurred simultaneously on my Asus Zenbook laptop running Windows 11. The issues are as follows:The inbuilt speakers have stopped working. Sound will still play through hardwired or bluetooth speakers or headphones.The media keys controlling e.g. volume, brightness etc. will no longer 'lock'. I previously had it set that I held 'fn' to use the regular function keys f1-f12, but that without fn held the relevant keys would control brightness etc. Now it has revered to having to hold 'fn' to do the latter. You can supposedly cycle between these

ESC and Function keys not working in ASUS laptop

Hi everybody, suddenly few buttons (ESC and Function keys not working in ASUS laptop) of my ASUS laptop have stopped functioning. Any clue what went wrong?

 

Sound - speakers/headphones - stopped working on ASUS laptop

Okay, some comments and questions:

1. Where in the Update History do I look (is this Windows Update?)
2. What is that "that" about which you're asking if I have it reinstalled again?
3. No yellow triangles in DM
4. Troubleshooter was useless. It told me that the speakers were disconnected. And once when I had updated a driver, it told me I needed to reboot.
5. I did read up on the Kyhi boot ISO you mentioned. Apologies, but what do I then do - boot from it and it tests all the peripherals including sound?

Thanks.

 

Sound - speakers/headphones - stopped working on ASUS laptop

With no intervening "event" - no new hardware or software or drivers installed Following the installation of a Cisco VPN client, the sound stopped working on my ASUS laptop.

There is a red X over the speaker icon at the bottom right of the computer. Mousing over the icon, one sees "no speakers or headphones are plugged in."

The computer had Conexant audio, plus AMD hi-def audio (I don't have the computer with me now, so this could be an inexact listing).

First thing I tried was to update the drivers, but both were up to date. I then uninstalled the Conexant via the device manager and restarted. Upon restart, the red X was gone, but I was still not getting sound. I could adjust the sound properties by clicking on the speaker icon in the system tray, but there was still no sound.

I believe I tried this again, and upon restart, the Conexant was gone from Device Manager, leaving just the AMD hi-def. I tried changing the driver for this to the generic Windows hi-def audio driver, but that didn't work.

I tried just about every trick I could google up:

• Download next drivers from AMD/ASUS/Conexant's sites
• Run sfc /scannow from an admin command prompt (everything was intact)
• Restart the sound services, and make sure they were on automatic start
• Seemingly a billion computer restarts
• Many I can't remember now

None have worked. And again, Conexant had been the default audio, then disappeared (why?). Now when I go to my "Sound" from the control property, AMD hi-def is the only thing showing in the playback tab, and it says "not plugged in" with a red down arrow next to it. The system tray speaker icon has a red X over it and left-clicking on it launches troubleshooting, which (un)helpfully tells me the sound isn't plugged in, after "churning and churning" for minutes.

The optical drive is the only thing I'm comfortable "opening up" on a laptop! Is there a chance that MAYBE something somehow DID become unplugged internally?

The only "bag of tricks" angle I've not tried is a system restore to four days ago, before this condition started.

Ideas?
