a great article on using multiple audio devices with JACK

I’ve been meaning to write a tutorial describing how to use multiple audio devices with JACK, using the “alsa_in” and “alsa_out” tools, but as it turns out, I don’t have to now! Linux Home Recording is a new-ish blog that already has a number of great articles about various Linux recording topics, and the most recent post there is all about using alsa_in and alsa_out.

It pays special attention to one of the most common cases — using a USB microphone — so it’s well worth a read.
