No sound for KVM virtual machines

Output of "sudo virsh dumpxml UbuntuStudio"
Description of problem:
I have Ubuntu Studio, a sound-editing-oriented distribution, running in a domU. In virt-manager I have added two sound cards, an es1379 and an sb16. Running lspci in the domU does not show either of them, and the OS is not able to play any sound, lacking a usable sound card. I had the same problem when using only the default es1379.
The output of virsh dumpxml (attached) shows both sound cards, but here is the output of lspci on the domU:
00:00.0 Host bridge: Intel Corporation 440FX - 82441FX PMC [Natoma] (rev 02)

I am using virt-manager-0.7.0-5.fc11.x86_64 and kernel-18.104.22.168-43.fc11.x86_64.
Thanks, but this is a known issue. See bug #508317
