Hi all, A new Realtek HD audio driver  (6.0.9261.1 A10) was released on January 6, 2022, please check to see if it solves the issue.
To give context we have a lot of 5420's and getting more in as we speak. There is a common problem that is coming up on them that are driving my team crazy trying to fix. Seemingly at random users headsets either mic, speakers or both stop working in Microsoft Teams. We have tried reinstalling all the audio drivers, reprofiling users and even reimaging the laptops. Some of these things work for a while but then the issues return. We are at a loss with how to fix this issue and with more and more 5420's rolling out to users it's becoming a bit of a nightmare.  Has anyone else had similar issues or know what is causing this problem and know how to fix it?
