No sound in Ubuntu

Hi everybody,

I have spent all afternoon trying to make Tidal work on Ubuntu, and I think I'm close to my goal, but there is a (hopefully) last thing to do. OK, I installed everything needed (with supercollider v.3.9). I open supercollider IDE and run "SuperDirt.start". It seemed to go well if it had't been for a "could not initialize audio." message. This is the full log:

*** Welcome to SuperCollider 3.9dev. *** For help press Ctrl-D.
Couldn't set realtime scheduling priority 1: Operación no permitida
SCDoc: Indexing help-files...
SCDoc: Indexed 1345 documents in 0.67 seconds

could not initialize audio.
RESULT = 0

When I run "d1 $ sound "bd sn"" on Atom it shows "Prelude Sound.Tidal.Context| tidal" what, as I've seen in livecoding videos, seems to be right. But I'm getting no sound.

Anybody knows why is this happening?

Thanks

Right! It was a jackd thing. After some configuration I found elsewhere that I had to run it this way: jackd -R -d alsa -d hw:1,0 using the format -d hw:CARD,DEVICE. Man, that was a tricky setup, but everything is ready now.

Thanks for addressing me to the solution.

you're welcome.
there are many (at least 3) front-ends for jackd that could be useful.
