I'm having problems with my sound forwarding from Hydrogen (http://www.hydrogen-music.org/hcms/) to Ardour through JACK audio connection kit.
I can't hear the sound from hydrogen if I play it through JACK (or in any way) to my sound output or play it throught Ardour (live I mean), but if I export sound from Ardour to file, when it plays I can hear the sound, I want to play it throught my headset (USB G35).
(system likes to set my hardware in sound settings to my graphics card (ATI HD5870))
I have installed QjackCtl as my "GUI" for JACK.
Also, all of these have been installed with apt-get.
I have made audio group and added myself into it.
Also I have gone throught alsamixer settings, no difference.
