Also still seeing this issue after trying the resolutions mentioned above. Other applications audio works, just not Minecraft on my windows 10 pc. Sound does work on my windows 11 laptop and on my switch and android. At this point I've reinstalled and updated drivers so many times, I'm not sure what's left to try.
--Thank you
From windows application logs it appears to be related to UCRTBASE.dll
The same as MCPE-112913
Log folder in %LocalAppData%\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe is empty
