Скажу сразу, что проблема повторяется на всех вёдрах (generic, rt, lowlatency), проверил на двух дистрах: Fedora 19, UbuntuStudio 13.10.
В общем стартую джек с минимальным рабочим буффером (128) для E-MU 0202 USB, включаю guitarix, играю значит сижу. Постепенно происходят всяческие xrun-ы. А потом бац! И всё, зависон, звука нет, никаких сообщений от jackd об xrun-ах, только одно сообщение от альсы:
ALSA: prepare error for playback on "hw:USB" (Broken pipe)$ jackd -dalsa -dhw:USB -r96000 -p128
