boyz, as a longtime user of multiple ice1712 cards (4) in a 'multi' array, one thing envy24contol never offered was a way of "assembling" or even seeing multiple cards from within a single instance. You can of course address different cards with the -c option, but it would make sense if this could be done within the a single instance; and given that it writes it's own config/.asoundrc type file then would it be possible for mudita24 to create a multi card array easily? i have always, like John Rigg, made my own .asoundrc(thanks John!) to run the alsa multi plug which just runs at boot, but this can be very difficult for the neebie to even understand let alone create themselves and it would be good if each card had it's own 'page' for tweaking and metering within a single app instance. whilst you're doing this fine work I thought I'd chime this in. 2c g.
