Right now, sound goes to EVERY channel (8 ADAT channels, AND the coaxial/SPDIF stereo). I would like to be able to route sounds separately, as the ADAT channels go to an ADAT deck (limted to 48k), while the coaxial/SPDIF line goes to converters which can handle 96k. I would love to be able to do both.

I would love to be able to do both. i would love to be able to answer you (as the driver author), but this is not at all a hammerfall specific question, and the answer is not well documented at this time. the method is the same for all ALSA supported devices. if you search the archives for "ttable" you will get some clues. i am sure that others who have done this will be able to give you better answers. --p ^ permalink raw reply [flat|nested] 3+ messages in thread

I would love to be able to do both. You are suffering from an erroneous decision of ALSA team when it was changed a feature of the PCM API (0.4 to 0.5 transition): file descriptors were bounded up with channels, now is bounded up with cards. Separate operation on multichannel card is easy at application level. However, low-level operations (i.e. routing) for each channel at kernel level is unnecessary complex.
