I can't hear Hydrogen

I recently installed Hydrogen on my computer, which runs on Ubuntu 14.04. It looks great, but I can't hear it. I've been fiddling with it for a couple of weeks, haven't been able to figure anything out.

On the Audio Systems preferences tab, the setting is "auto," and, no matter what I change it to, it apparently reverts to auto when I close it, because that's what it's on when I open it back up. I do have Jack on my computer.

Searching this forum for "can't hear hydrogen" turned up no items. I did a general search for this problem, and the only query I came up with got no answers. It was a few years old. I hope I can get a better response than that!

Thank you!

An update--apparently it only becomes audible when I have Audacity open. I've been thinking about switching back to Ardour for recording, but it is being temperamental about working at the moment. May have to do with not having my recording interface plugged in. It would be handy to be able to run Hydrogen without having to open Audacity, although it's not a serious hangup. I think it has to do with Hydrogen being a "slave" to Audacity? If somebody could shed some light on this for me, I'd appreciate it--or maybe I'll keep figuring it out for myself.  :-)

 

I would have to restart the computer to plug in the interface and see if Ardour works then. Will report on that another time.

Hi Martin!

I believe that there might be multiple problems there. First of all, we had a bug with the "auto" setting in an earlier version of hydrogen which made it hard to save other settings, so for this particular issue, it might help to get a recent version of hydrogen (maybe built it from source). But besides that, it sounds more a problem with setting up the Ubuntu environment as with Hydrogen.

If you want to use jack as an audio driver you could try to start jackd before you start hydrogen.  This helps hydrogen to detect jack with "auto" setting. In addition, you can tell hydrogen which sound driver it should use by using a command line parameter ("hydrogen -d jack"). Maybe this helps?

Thanks! I downloaded Hydrogen from the Ubuntu software center just a few weeks ago, so I think I've got the current version. I will try starting Jack first the next time I open Hydrogen.
