Hi,

Not sure if that helps you much but it appears you’ll have to get a different audio capture and mix them.

I can’t confirm how accurate the above statement is regarding Red Hat support but found this statement on the ViewCast website.

> For select Osprey® PCI™ and PCI-X™ cards, Linux support is available from the Linux Open Source community. Modern Linux kernels include a module that supports the chipset on the PCI/PCI-X capture cards. Please note: these drivers are supported by the Linux community and not by ViewCast.
