You have to configure audacity with: --with-portaudio=v19 --without-portmixer Think it's a kind of bug of either audacity/portaudio, we will have to wait for it to mature. Now I tried to use alsas jack plugin, (and configured asound.conf accordingly) Without success: ## aplay -Djackplug kent.wav ALSA lib pcm.c:2052:(snd_pcm_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_jack.so aplay: main:533: audio open error: No such file or directory Has the jackplugin been removed from alsa 1.0.9b ? emanuel
