I don't have a RME card and don't entirely understand how this works, but I think the informtation you need is related to alsa pcm plugins and ttable definitions which you need to define in a .asoundrc file... I know that is somewhat vague, but here are some references that may help: http://www.alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html The links under Configuration on this page: http://www.alsa-project.org/alsa-doc/alsa-lib/ http://alsa.opensrc.org/index.php?page=AlsaTips I'm pretty sure this has been discussed on the list before, so the archives probably have something on this as well. -Eric Rz. _______________________________________________ Alsa-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-user
