KB5052093 Windows 11 Cumulative Update Preview build 26100.3323 (24H2) - Feb. 25
Fixed: A USB audio device might stop working after your PC is idle for a short time.
This might have something to do with it.
Ever since upgrading from 23h2 to 24h2 my keyboard has a weird issue. Whenever my PC sits idle for a while my volume buttons don't work unless I left click my screen with my mouse. Microsoft Natural Ergonomic Keyboard 4000.
Any Ideas ?
