Out of the box, there are no drivers for the emulated Sound Blaster 16 for Windows Server 2003 R2. You can get sound to work if you use the drivers that come with Windows XP.
First copy the following files from the Windows XP CD.
- WDMA_CTL.IN_ (from the i386 directory)
- ctlsb16.sys (from the Driver.CAB file in the i386 directory)
You will need to expand the WDMA_CTL.IN_ file. From a command prompt type:
EXPAND WDMA_CTL.IN_ WDMA_CTL.INF
These two files WDMA_CTL.INF and ctlsb16.sys are the Sound Blaster 16 drivers. Copy them to your Windows Server 2003 R2 Virtual PC.
Now in Device Manager choose "Install from a specific location (advanced" and browse to where you copied these files. The driver will then load.
Now in Services ensure that the "Windows Audio" service is set to "Automatic" and is started.
Lastly, under control panel, you can choose to add the volume icon in the task bar and choose a sound scheme.
