What hardware/kernel/distro versions work OK and which don't? Especially important is the motherboard chipset, ALSA version and exact make/model of soundcard. My guess is that different soundcards default to different period/buffer config values, and that Audacity wrongly assumes the buffer/period size it gets from ALSA by default is sane on all hardware.
