Hi all, I've got a DreamPlug (successor to GuruPlug and SheevaPlug: <http://www.globalscaletechnologies.com/c-5-dreamplugs.aspx>) - it's very close to being a plug-and-play little ARM-based Ubuntu 9.04 machine. It's got audio in and out, and optical audio, so I'm hoping I can get it set up as a generative audio box. The audio works - "aplay" works straight away for playing back a wave file. (I might as well mention that the build quality is a bit ropey: the headphone jack doesn't quite stay plugged in properly, and nor does the power cable extension that came with it.) Now for jackd and friends... I installed jackd 0.116.1 from the official repo (BTW, the official binary package for this platform doesn't have alsa enabled -- I did "apt-get source jackd" then manually built it with alsa enabled). I installed supercollider from the latest git. Supercollider can do an offline render of a wave file, and aplay can play it back. But I can't seem to get any audio from a jackd-based pipeline: neither using supercollider, nor using "jack.play" from Rohan Drape's tools. (jackd doesn't report any problems: <http://pastie.org/2092598>. I'm not familiar with oss at all but jackd fails to start when using it: <http://pastie.org/2092634>) So, questions: * How to troubleshoot the jackd setup over a pure-CLI connection? I could use GUI tools over X forwarding, but given the smallness of the box I'd prefer to avoid installing GUI libraries etc. A commandline jack-level-meter would be nice, if anyone knows of one, to verify that sound is reaching jackd from its clients. * Have you got jackd working nicely on similar systems (Linux ubuntu 2.6.33.6 #1 PREEMPT Tue Feb 8 03:18:41 EST 2011 armv5tel GNU/Linux), and have any tips?
