Installing Skype on Amazon EC2 instance

For my application, I need to have Skype working on my Amazon EC2 Windows instance. I got the application installed and am able to log in, however, I c开发者_运维知识库an't make a phone call, since I am getting an 'Can't detect your sound card' error.

Since I'm trying to inject audio from an audio file into the phone call, I don't need the sound card on the server. Thus, I need a way to bypass this error message.

I have tried installing Virtual Audio Cable, which unfortunately didn't work (even though it worked on my desktop machine).

Turn on the Windows Audio Service (and the dependent services as well):

Edit: version 3 doesn't work in windows 2008 server.

Did you try Virtual Audio Cable 3 instead of 4?
