No Audio/Sound in Windows Server 2008 Guest on GNU/Linux Host

[vbgunz]

In regards to VirtualBox 2.1.2. Audio works in Windows XP as a guest on Kubuntu 9.04. It uses PulseAudio/ICH AC97 without a problem. Unfortunately the same cannot be said for a Windows Server 2008 installation.

I've enabled audio in WS08 *but* still see "No Audio Device Output is Installed" after logon. Checking sounds in Playback/Recording say "No Audio Devices Are Installed". I checked device manager and it just cannot seem to find an audio driver.

Is a driver included and not correctly installed? Sorry if one is separately available I cannot manage to enable it or find it.

I'm having the same problem using an XP Pro guest on a Windows Vista 64-bit Host. I'm trying to run Cisco VPN Client software on the XP since it won't run on a 64-bit system (way to go Cisco!). I need to get the audio working on the XP. Any ideas? I tried installing drivers, but they cause system errors. I have the null audio driver (AC97) installed but it will not find the host audio. It says "no audio devices installed". I have the audio enabled in the settings page. Please help! Replying to vbgunz:

I have similar problem using Windows 7 Ultimate RC as the guest with Ubuntu 9.04 (jaunty) as the host OS. A virtual XP machine on the same host can use sound fine, but Windows 7 reports that it cannot detect an audio device (PnP). The guest OS troubleshooter is no help.

Is there a way to manually install the virtual device under Windows 7 RC instead of relying on auto-detection?

Replying to dave.uggla@gmail.com:

Additional information: With audio disabled in VM settings, I do not detect an audio device. With audio enabled and using either ICH or SoundBlaster configured, Windows 7 reports that it cannot find a driver.

Well, that was quick. A little more experimenting shows that although Windows 7 RC did not have either driver available and (apparently) failed in its search for a compatible driver, there is an AC97 driver out there.

Once the setting in VirtualBox for the AC97 driver was made and the guest rebooted, the Windows Update site suddenly offered an "important" download of a new Intel Audio Driver. Once that update was applied, the sound started working properly.

Possibly the beta carried more drivers with it than the RC, since I did not find anyone reporting problems with the Windows 7 beta.

Note also that I had gone through Microsoft Update/ Windows Update numerous times before setting the emulated card to AC97 and no updated drivers were offered.
