[LAU] Ardour session with plain ALSA, without JACK

[Ralf Mardorf]

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.

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.

$ pacman -Q ardour
ardour 4.7-1

$ grep jack /var/cache/aur/current/ardour-4.7-1-PKGBUILD
--with-backends="jack,alsa" \
--libjack=weak \

$ amidi -l;aplay -l;arecord -l
