Hello everyone!
I just tried to give JACK a real cardname on the commandline instead of the
hw:0. Reason, there are several soundcards in that machine, including USB
devices. I looked at /proc/asound/cards and copied the name "M1010LT". And
then I ran this command:
jackd --timeout 4500 -R -d alsa -d M1010LT -r 48000 -p 128 -z shaped
JACK told me, that M1010LT caused an ALSA open error, since the device was
unknown. This is JACK1. JACK is run by a user with the necessary rights and
limits set. With -d hw:3 it works.
Whilst I'm here, I might as well ask, what the easiest way would be to
automatically start JACK, when the system boots? If that helps, the system is
running a graphical session and I believe, this could be the case constantly.
So if there's a typical solution involving that, it could be a way.
Thanks for any help on either of those.
Warmly yours
julien
