That's probably ok then, am I getting this right that the the DSP card would not expose any USB-related kcontrols then, i.e. the ONLY path to change volumes, etc., would through the regular USB card kcontrols?
That would limit the changes in the platform sound card to the addition of a PCM USB device.
I'd guess that there might be some volume control in the DSP as part of the generic routing to the port (eg, if all ports have some output control) but I'm not sure that's an issue, could even be useful for normalising the output of DSP algorithms compared to direct PCM playback.
