Open the PCI-324 Console, or open the Configure Hardware Driver Window(if you are using AudioDesk or Digital Performer), and assign Bank C to AES/EBU. Enable the input and assign the Output Source as "From Computer". If you have the "Enable Routing " button unchecked we will assign the input and output for you. You will just have assign Bank C to AES/EBU.

Whenever recording a AES/EBU source you must set the Clock Source to "1224-AES/EBU" or to the corresponding AES/EBU input with a 308. Make sure the Sample Rate in the console also matches the Sample Rate of the AES/EBU source.
