Hi, why not using jack with the ALSA backend, together with pulseaudio or without pulseaudio at all, instead of using ALSA directly? http://www.jackaudio.org/ There might be reasons to not use jack, but at least for multi-track recording this IMO is the best and easiest approach. FWIW Ardour now allows to use ALSA directly, seemingly without the need to set up ALSA on your own. I couldn't test it, since it doesn't work with all RME cards, but most likely there are no issues with Envy24 (ice1712) cards when using Ardour. IOW depending on what you want to do, consider to use jack and/or Ardour. Regards, Ralf ------------------------------------------------------------------------------ Transform Data into Opportunity.
