Maybe the device is busy (used by jack)? Could you run this diagnostic tool: wget http://jackaudio.org/downloads/adevices.sh && bash ./adevices.sh It'll print all soundcards, processes that currently use them and settings. If you launch Ardour from a terminal, maybe there's also more info printed to the console. Last but not least try a demo debug version from http://nightly.ardour.org/ to rule out potential mistakes from distro packages. > There's no special reason that I want to use ALSA instead of JACK, I > just want to test it.

One reason would be to compensate for systemic midi latency (Ardour's ALSA backend can do that, jack can't). best, robin _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
