I finally found a driver for win7 64bit which is working with the ac97 sound card: http://www.64bitdrivers.com/driver.php?id=1375
If you download the driver sk35558.exe and edit the inf file for the PCI IDs used by kvm it will install with a warning about unsigned code. Add the following line to the [Conexant.NTamd64] Section in the file cp6308Ba.inf: "%*WDM_AMCAUD.DeviceDesc%=WDM_AMCAUD,PCI\VEN_8086&DEV_2415&SUBSYS_00008086" I think this helps to mitigates the issue till we update to a new version with hda sound support. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/419182 Title: KVM and audio driver in Windows 7 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
