I have Virtual Audio Cable successfully installed on my Windows Server 2008 R2 SP1 x64 virtual machine. It seem like driver works (new audio device in Device Manager group and VAC control panel works perfectly), but unfortunately if you go to Control Panel -> Hardware -> Sound there is no audio devices (neither playback or recording). And so my software doesn't see any audio devices.

It is virtual machine with no physical sound card. I connect to it using Remote Desktop.

Is this known issue? Is it possible to get VAC working on such machine?

Audio is special in a lot of ways, and audio drivers run in the context of a "session" in Windows, so each remote desktop user gets their own audio. Even on a physical machine, when you connect via remote desktop, you see different audio devices in device manager from the ones you see sitting a local keyboard.

The short answer to your question is that a VMware virtual audio device will only be visible in the "console" session, not in secondary remote desktop sessions. You can remote audio through your remote desktop, with our without a VMware virtual audio device.

I have tried to run in the "console" session by using MSTSC /admin. But I have the same results. No audio devices there. –  Pavel Shchegolevatykh Aug 9 '12 at 8:37
    
The console session is only available through MSTSC /admin for Windows Vista and earlier systems. Windows 7 (and Server 2008 R2) have no such console-over-MSTSC notion. If you want the console, you're going to have to use VMware redirection tools, whatever you would have used to see the boot manager and boot process. –  Jake Oshins Aug 9 '12 at 21:40
    
What if I install Windows Server 2008 or Windows Server 2003 on my machine? Is it solve this problem? –  Pavel Shchegolevatykh Aug 10 '12 at 11:29
    
It's not clear what problem you think you're solving. MSTSC will remote audio, with any of those operating systems. Instead of using that, you're trying to use VMware mechanisms for remoting audio. That's fine, but for me to answer your question, you have to tell me why you want to use VMware means rather than the built-in Windows one. Then I'll know what your goals are. VMware might offer sound during the boot process, or some level of 5.1 Dolby or something that MSTSC doesn't. Is that why you're trying to use it? –  Jake Oshins Aug 11 '12 at 2:13
    
For example I need to make call in Skype for some phone number and play custom sound (*.wav file) in this machine. But as I said it is virtual machine and it doesn't have any sound devices. In this case Virtual Audio Cable helps. It installs virtual sound devices (speaker connected with mic) that allows to transfer all sounds to mic. This works perfectly on physical machine (even with disabled sound card in Device Manager). I want to get it work on my virtual machine. –  Pavel Shchegolevatykh Aug 22 '12 at 9:33

Virtual Audio Cable works fine with 2008 R2 , but it needs to be installed on a session basis, it will not replicate over RDP, you need to connect with Team Viewer or something similar to access the audio streams.
