I've been improved ALSA dice driver for years with the other drivers, but it doesn't bring so hasty changes since it's a kind of reverse-engineering; no one knows the actual design and few ones can make discussion based on the fact. Well, I also own TC Electronic Sudio Konnekt 48 and I've investigated its protocol to configure I/O routings on internal DSP. After my vacation, I'll send information about it for your convenience (maybe next week). Regards Takashi Sakamoto
