[Spice-devel] the audio do not work in remote-viewer for windows

[gianpietro.sella at unipd.it]

Tanks Fabiano.
In my new build of spice client usb redirection work very well.
the problem is audio redirection.
For my test, to build new client windows cross-compiler mingw, I use linux
VM in the openstack cloud system.
Now I install new linux fedora 23 and I build windows client remote-viewer
with mingw-virt-viewer.spec.
I hope this solves my problems with audio and msi tools.
Merry Christmas and happy New Year.
Gianpietro.
