problems running rezound on a friend's computer

Hello, I've been trying to get rezound working on an installation of 64studio I did for a friend. It's a fairly old machine with an on board sound card (can't remember sound card model). Rezound starts up OK but when recording from alsa there are regular clicks in the audio. If I record through jackd instead (starting qjackctl before rezound), it records OK but won't then play the recorded sound - when you press play it just sits there doing nothing. I would really like to get this program woring for my friend, as the interface is much friendlier than audacity and he seems to like what he's seen of it. If anyone has any suggestions for things I could try (short of compiling a custom install of rezound), that would be good. Alternatively, maybe the 64studio team could make up a 64studio package for rezound and put it in the backports repository? (At the moment it is just a debian package). I think this would be worth doing as rezound is a really nice sound editor when it's working, and it's a shame if people can't use it at the moment. andy
