Yes, stop replacing the mvp-2.dll file and install the proper codec : [image] [BUG] Problem with (E-)AC3 Codec and Windows update 24H2 Desktop Players I am having the same problem, is plex going to reply on a way to fix this? I do not want to install AnWave as it is imme…

I fixed it with those solutions too at first but there were these ugly programs in my applications so I fixed it with WinUtil Documentation instead as well as the tool can do a great other many things to boost performance and privacy. I used the config tab to install legacy media features

After installing I closed/re-open the Plex Desktop app and I have audio a…
