[ovirt-users] Windows 7 guest not synchronize sound on ovirt 3.5

Hi all, We are experiencing a problem when accessing Windows 7 guest over virt-viewer client... although I increase/decrease the volume on Windows guest speaker... it remains always at the same level... Seems that there is no synchronization with the Client. Andy clue about the problem? and if it's a known one? BRgds, F.
