2.6.32-251.el6.x86_64
qemu-kvm-0.12.1.2-2.265.el6.x86_64
# rpm -q seabios

guest info:
guest_name: win7sp1-64
virtio-win: virtio-win-prewhql-0.1-24

How reproducible:
100%

Steps to Reproduce:
1.plug the Multimedia Speaker to the host and get USB device info var "lsusb".
# lsusb
Bus 002 Device 015: ID 0c76:160c JMTek, LLC.
2.boot a windows 7 guest and passthrough a Multimedia Speaker device to the guest with spice console.
CLI: # /usr/libexec/qemu-kvm -M rhel6.3.0 -cpu Penryn -enable-kvm -m 2048 -smp 2,sockets=1,cores=2,threads=1 -name win7-sp1-64 -uuid `uuidgen` -drive file=/home/win7sp1-virtio-64-copy.raw,format=raw,if=none,id=drive-virtio-disk0,cache=none,werror=stop,rerror=stop -device virtio-blk-pci,scsi=off,bus=pci.0,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -netdev tap,sndbuf=0,id=hostnet0,vhost=on,script=/etc/qemu-ifup,downscript=no -device virtio-net-pci,netdev=hostnet0,id=virtio-net-pci0,mac=05:1a:4a:02:0b:46,bus=pci.0,bootindex=2 -device virtio-balloon-pci,id=ballooning -spice disable-ticketing,port=5931 -k en-us -vga qxl -global qxl-vga.vram_size=67108864 -monitor stdio -device intel-hda -device hda-duplex -usb -device usb-host,hostbus=2,hostaddr=15,id=hostdev1,bus=usb.0,port=1
3.play sound inside kvm guest and check the Multimedia Speaker.
example: select many songs online playing from www.9k.com
4.verify the device is present in guest from "Device Manager".

Actual results:
after the step 3, the Multimedia Speaker fail to work, we cann't hear anything from the Multimedia Speaker. 
after the step 4, we can find "High Definition Audio Device" and "USB Speaker" from "Device Manager" in the guest.

Expected results:
the Multimedia Speaker can work well and we can hear the music sounds smoothly.
