Apparently, I'm running arts. Great. One more thing I don't really understand. Now, I've been to arts-project.org and see that it's the Analog Realtime Synth, blah blah blah. Questions: do I need it to capture audio from the sound card? Should I be trying to trouble- shoot it? Or is it getting in the way of things? artsd --help says you can select ALSA as the IO method. I wasn't able to select it from the KDE control module, though. That a problem, ya' think?
