I'm not sure if I undertand the question. The 1010 has 8 analog inputs/outputs plus spdif. There is an internal (in the chipset) digital mixer that can be used to do a mixdown to stereo. There is a digital patchbay that defines what goes to the outputs, you can select any input or spdif channel and the outputs of the internal mixer (channels 1/3/5/7 can get the left, 2/4/6/8 the right). The app to use to control all this is envy24control and is part of the alsa-tools package. -- Fernando
