ALSA seems to work fine - I managed to use Hydrogen successfully with AlSA output. The card also worked recently in a Windows machine. >From a discussion on the PlanetCCRMA list, it seems likely that JACK settings need to be set to something unusual. > By the way I'm running UbuntuStudio. I'm running PlanetCCRMA on FC6.

Start with periods=8 and see what it tells you (you > may need to get the buffer down). When I tried this, JACK started successfully, but I got many xruns.
