I've been having the exact same issue with my Asus Zenbook for nearly 10 days, but I also have no sound from internal speakers. I've uninstalled and reinstalled drivers, searched endless pages on the internet and even went so far as to completely uninstall and reinstall a fresh version of Windows 11. Updated BIOS, etc. NOTHING HAS WORKED! I finally got a Bluetooth headset to work, but only the audio, it won't recognize my headset's mic. My entire Dolby Atmos system also will not work.
The Intel(R) Smart Sound Technology (Intel(R) SST) OED listed under System Devices in Device Manager had a yellow warning triangle next to it. Everything I have found on the internet says that there is a known incompatibility between this device and Windows 11 going back years. No amount of updating or trying to disable / enable has solved the problem. I renamed the driver file so the startup process couldn't locate the driver and reinstall it, but that only gave me temporary sound - and still no mic!
I'm pretty sure at some point I had a Realtek sound driver, not an Intel driver, but I honestly can't be sure, and trying to locate 2 year old Realtek drivers to see if that works is proving to be another nightmare on top of the one I am already living through. I have spent DAYS on this with no solution. And also submitted a ticket to Microsoft.
Beyond frustrated by the lack of support and solutions to this known issue.
