We are unable to provide Windows 7 drivers for the Sirocco and Callisto. the audio driver system in Windows 7 is just too different from Vista for our supplier to be able to convert them. The products came out many years before Windows 7 was released and are, unfortunately, incompatible.
NOTE: The Sondigo Sirocco does not currently have support for Windows 7. We are still working on it, but at the present time we do not have a compatible driver. Please check back soon for more information -- it will be posted as soon as we have an update.
Some users may be able to install the driver using the Windows 7 compatibility mode -- depending on their system configuration. We are working through the issues to try to get a general solution ready.
A Beta Windows 7 Driver is available for the Inferno, from C-Media:
We are working on Windows 7 Support for the Sirocco and Callisto. Please stay tuned.
