My Steinberg/Yamaha UR22 doesn't have a driver that allows it to process and record loopback signal (for the purpose of recording spoken-word interviews with remote guests from my home studio). I previously had an EMU 1820m, and it did have such a loopback patch which allowed me to monitor and record host signal by routing a logical loopback input), but it croaked after many years and I last week replaced it with the simpler UR22.
Steinberg/Yamaha's support advice is to buy a more complex hardware array which happens to be packaged with a much more elaborate driver library to include such a loopback function in its audio mixing software, but I do not want to buy all those various hardware functions when all I need is the microphone jacks in the relatively simple UR22 hardware interface. Problem is, no loopback patch came with the UR22 software bundle, and I have asked if they'll give me one but they haven't responded yet, and I anticipate a "no".
So, I think I'll migrate my audio studio over to my local fileserver, which is running Slackware 14.1, and install the the UR22 hardware on it. My reasoning is that I can just put in a mixer software; Either OSS (

http://en.wikipedia.org/wiki/JACK_Audio_Connection_Kit) and/or PulseAudio (
http://en.wikipedia.org/wiki/PulseAudio) and/or ALSA (
http://en.wikipedia.org/wiki/Advance...d_Architecture), and then I should be able to come up with some sort of logical loopback patch that will allow me to move forward with my audio studio operations without having to buy additional new hardware.
My questions are, 1) What are the community recommendations/caveats/scuttlebut regarding the above-mentioned Linux-friendly audio projects, and, 2) In the shadow of any advice from question one, how best might I go about patching a loopback functionality on the slackware system?
All my very Best,
