After Windows 11 pro insider preview update on February 8th 2024 I have lost all audio

Windows 11 Insider Preview 10.0.22504.1010 - UPDATE FAILED

This may have same issue which is listed build 22504 release announcement as "know issue".

• Some devices may bugcheck with error code 0xc1900101-0x4001c when installing this build. If you hit this, after the device rolls back to the previous build, you may want to pause updates until we release a fix.

In future I recommend to post insider related questions to dedicated Insider Forum.

Surface Pro 3 with Windows 11 Insider Preview OS vs. Surface Pro 4 with W10 Pro that cannot upgrade to W11

Two questions:

1. My Surface Pro 3 continues to download and install W11 updates on the Insider Preview Channel. How long might I expect to have access to updates? In other words, will I lose access and be forced to revert to W10?
   
2. Can I enroll in Windows Insider Preview on my Surface Pro 4 and upgrade to W11 Insider Preview?
   

I'm finding more and more to like about W11 and would certainly prefer to continue to move forward, not backward.

 

Windows 8.1 pro to windows 10 pro/insider preview upgrade

I've noticed that, after the upgrade is downloaded, the main page of windows update displays Windows 10 pro insider preview. On all other pages, including list of past failed upgrade attempts, the update is displayed as Windows 10 pro. Which version of Windows
am I getting?

I'd rather not go to the insider program.

Thanks in advance.
