I have a 2008 R2 server set up as a remote desktop server. Using IE11, HTML5 videos won't play.

Desktop Experience feature is installed, and IE ESC is disabled for both users and admins.

However it works fine if logging into the console, so only a problem over RDP.

The only suggestion I've found online is disabling IE ESC, but that is already disabled.

Anyone have any ideas?

EDIT: The server is a VMware virtual machine, in case that is relevant.

EDIT 2: The plot thickens. If I don't map audio through to the client, the video plays fine (but without sound obviously, so not a solution).

Have you got VMWare Tools installed?

Mattmannz:

Sure do.

Audio is working, e.g if i put youtube.com in compatabilty mode it plays the Flash version of videos and both video and audio are fine.

I can replicate this on a physical 2008 R2 server, so it would seem nothing to do with it being VMware.

Found the solution.

KB2483177 not released under Windows Update.

Strangely all the file listed in the hotfix are actually older than what was already on the system, however it looks like the audio codecs weren't correctly registered.

The installer appears to have just gone ahead and just put the current versions that were already on the sever into System32 and SysWOW64 and register them (presumably recognizing the newer files were already available on the server, but not registered).
