Sound from Win 7 VM


Has anyone got audio playing and recording from Win 7 to to KVM host? I know that audio recording is restricted and will not work on Win 7 Professional but it should work on Win 7 Ultimate.

Any idea why sound doesn't seem to work for me, I am using the default VMM choice of ich6 for the sound device.

Edit:
Forgot to say I have tried the AC97 device but windows cannot find a driver for that.

I found the spice drivers the best way to get sound through KVM. Also had some luck with doing it through remote desktop.

ac97 has no drivers for win7x64, try it with win7x32 - should work just fine. Especially with spice

Are you suggesting going back to 32-bit Windows rather than 64-bit? Unfortunately in this case that is not an option, must keep to 64-bit Win 7 for other reasons.

I can see how to change the VM settings to enable spice but where can I obtain the Win 7 spice graphics driver from?

Sorry, wrong link. Try here - http://spice-space.org/download.html under "windows binaries"

You'll have to use a different sound card then. Libvirt has several options available, just make sure the one you use has x64 drivers available

That is very much the question, has anyone got any of these sound card options working in a Win 7 VM and if so which one. I have tried them all but so far no success with any of them.

I haven't, most of my windows VMs are servers, and the only one that is a desktop, is 32bit. If I have the time, I'll try and set up a 64bit win7 VM
