Davide, If you use KVM, it"s possible to enable audio. Please refer http://libvirt.org/formatdomain.html#elementsSound
Here is some infomation about how to enable it in nova: http://www.gossamer-threads.com/lists/openstack/operators/21302 Haven't test it, I think the steps should be: 1. cp /usr/lib/python2.7/dist-packages/*nova*/virt/libvirt.xml.template /etc/*nova/* 2. add next line to *nova*.conf --*libvirt_xml_template*=/etc/*nova*/libvirt.xml.template 3. Edit /etc/*nova*/libvirt.xml.template, add the following lines: <devices> <sound model='ich6'> <codec type='micro'/> <sound/> </devices> Hope this is helpful.
