Emulate a Sound Card in VMware ESX 3.5U4

HI All,

I am in the process of virtualising a number of physical servers, including a small number of Citrix servers.

On these Citrix servers there is a client/server application which needs to "see" a sound card. I stress "see" as the application only needs to see the sound card in device manager to load correctly. The virtual machine will never play any sounds.

The application is WinScribe. I have searched to see if there is something like a loopback sound card driver for windows and I have also tried editing the VMX file manually to include a sounds card, but to no avail.

The only thing I have got to work is a USB sound card, connected to a USB to Ethernet device, but this is far from ideal and I can't deploy a system like this.

Anybody got any suggestions?

Sound is not supported in the esx family
If you need sound for your VM you should create VM on vmware server/workstation

Btw, the latest vSphere has VMDirectPath feature that allows VM to access hardware directly, perhaps it can work with specific sound card but your server must support IOMMU

Hi ryder0707,

I know sound isn't supported in ESX. It's not really practical to have 5 or 6 Windows server instances running on VMware Workstation!

I suppose a different way to ask the question might be to forget about the fact that it is a virtual server - How might someone get Windows (running on physical or virtual hardware) to "see" a installed sound card?

OK as i mentioned before, perhaps VMDIrectPath will work for you but you need the latest esx version

Oh how cool is that, creating a virtual device in a virtual system :)
