I am loving remote desktop in Windows Server 2012. One problem - I can't figure out how to enable sound. The usual remote desktop/terminal services tools are missing in 2012. (See tsconfig.msc / tsadmin.msc in Server 2012 on this site)
I have changed local group policy and set "Allow audio and video playback redirection" to enabled, which did not solve my problem. That's the only setting I can find.
