It runs here fine with ALSA (looks great, by the way,
thanks for the
nice work!). However, the JACK version locks up the terminal and the
process cannot be killed. in fact "ps" dies even trying to view the
PID, etc. I would be happy to try and better diagnose it if others
have a similar problem.
This is with Fedora Core 2 running PlanetCCRMA, kernel
2.6.8.1-1.520.1vR9.ll with "realcap" capabilities in JACK, an
otherwise bullet-proof setup.
In my case it runs with alsa and (only) segfaults with jack (FC2). This
is what I get if I build with "-g":
Program received signal SIGFPE, Arithmetic exception.
