whether they are clock synced or not. It just isn't a good idea and
isn't how a professional system would be built. It also isn't done by
using the -P and -C arguments to the backend, because this doesn't do
any resampling to keep the streams synchronized, but by using bridge
clients like zita_a2j.

Indeed, it sounds confusing to read that somebody wants to use RME audio
gear and internal HDA / sound blaster sound cards at the same time. For
language laboratory usage there might be the need to have as much IOs as
possible, without taking care about the quality, but for common audio
production we likely would use the RME gear and disable on-board audio
and similar crappy devices.
