Hi,
if I chose "Audio System: JACK" I can start a new session, but if I
chose "Audio System: ALSA", I get "Failed to open audio device".
Perhaps I make a mistake.
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. I never tried to do it before, with any other
version of Ardour.
One reason would be to compensate for systemic midi latency (Ardour's
ALSA backend can do that, jack can't).
best,
