Yeah, forgot about that. I'm currently using PulseAudio 1.1 on its stock
configuration, over ALSA. After trying a bit by loading the jackd module directly... and installing jack (1.9.9.5), I reverted to the defaults.

If it's of help, I have put the what's printed to the CLI racket REPL here: http://pastebin.com/Y6N3xgM6, the sound played once on that run as well.
