I don't see where the problem would come from in that situation. > Paul, I'm going to guess that the problem will be in the way the output data is handed to the Sound Blaster. Let's say that the underlying sound system (Alsa or whatever) is running off of the RME's clock. The data is brought into the system using the RME clock. It gets processed in the Linux environment using the RME clock, and it gets handed, as a block of data, to the Sound Blaster using the RME clock. This is the problem I think. The sound Blaster needs to have the block handed to it based on it's own clock rate. If not, then there will be times when the SB clock comes a little bit early and the data won't be ready to go since the RME clock hasn't happened yet. This will result in a click. I hope this helps.
