Short summary from the various mails on this list and from alsa-project.org: It is possible via an .asoundrc but you wont get it to work with jack without xruns. xruns are when one soundcard needs its new data (for playback) before the other card. It happens because your soundcards won't run with _exactly_ the same frequency altough all clame to to 44.1kHz/48kHz. There was a thread here (or on linux-audio-developer@?) where one disconnected the quartzes from the second and third soundcard and connected them with the one from the first soundcard. Another approach is syncing the cards via an external digital sound signal (not timecode)... > Any ideas?
