Hi everyone,

I'd like to use Csound on linux Librazik-2 (64-bit), but I am having the same issue I've had on Ubuntu-Studio previously. Namely, that I am not able to connect to Jack when a2jmidid is running.  The tag I usually used is -rtaudio=jack  but it gives an error of "Alsa device not running or not available."  I think this is due to a2jmidid running, which usually sends any alsa audio signal directly into Jack, if I understand it correctly.

Unfortunately, Csound continues to not connect.  -Or is there a different Csound option I should use?

Any help much appreciated!

brian

Do you mean -+rtaudio=jack ?

Well, good news! I had to deselect BOTH of the option boxes in QJackCtl: execute script before starting AND execute script after starting.

It would seem that Csound is not able to play nicely with both a2j and Pulse Audio when using Jack and QJackCtl.

I don't know if it's in the current manual, but linux users who can't get connected to Jack would do well to check to make sure that these options are not selected before starting QJackCtl. (some distros may have QJackCtl set up in such a way that scripts are set to run before/at start-up, and this will cause headaches for some!)

Of course, if Csound could just connect nicely to a2j, that would be the best, imo.  Because many synths for linux require a2j to run, so it's an important script.  At least for me.

Just a thought/suggestion, anyway.  :)

Thanks Brian. 

After many attempts over many years, in Ubuntu and sometimes Studio,
I've never yet succeeded in getting Jack or QJackCtl to work correctly,
simply or repeatably. 

It almost seems that Jack/QJackCtl just doesn't play nicely with
Ubuntu. 

Great you've had success.

I don’t know if it matters but jack and pulse audio doesn’t always like each other and I’ve read that the implementation of pulse in Ubuntu is heavily criticized by the pulse devs, so maybe that is an issue?

I’ve had jack working nicely in Debian at least, but then I have not even had pulse installed...

Also, Csound supports jack midi nowadays, so maybe that could be an alternative?
