Whatever you use, there will always be a delay difference between the main soundcard used by Jack and the added one(s). At least with the zita tools this will be defined and stable, so you can measure and then compensate for it. In many cases it won't matter much as long as you don't split a stereo signal over two interfaces. BTW, the page on the jack wiki pointed to earlier is completely out of date. Just ignore whatever is said there.
Could (or should) Studio Controls start zita automatically when connecting more than one soundcard? There's a setting in Studio Controls 'Bridge USB devices to jack when plugged in' that's on by default and maybe does exactly that.
But if so, it's not clear from the dialog whether this is done via zita or other measures. The manual at https://ovenwerks.github.io/studio-controls/extra-devices.html doesn't say this either, but the overview at https://ovenwerks.github.io/studio-controls/index.html states that Studio Controls "Allows multiple audio devices to use JACK at once".
So far my humble testing confirms that, for which I'm very grateful. Alf _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
