Since hyper-V doesn’t provide a virtual soundcard, there is no audio playback device installed on a Hyper-V guest server.
Opposed to Windows Server 2008, just setting the remote audio playback to ‘play on this computer’ in your Remote Desktop client doesn’t do the trick in windows server 2008 R2 though.
The playback and recording of audio over RDP in Server 2008 R2 is disabled by default. To change this setting you’ll have to do the following:
- Click Start, type remote in the Search Programs and Files box
- Select ‘Remote Desktop Session Host Configuration’ from the list of programs
- Right-click RDP-Tcp in the middle pane, and choose properties
- On the Client Settings tab, remove the ticks from Audio and Video Playback and Click OK
There will be a message that informs you that these changes ar only for new rdp sessions, so you have to logoff the session and logon again.
When logging on you should hear the login sound through your own computer.
