Ardour won't playback sound via headphones
I've just installed a new ubuntu 11.04 including ardour and I'm a bit surprised that I don't have to start the JACK daemon by myself anymore. Instead I just fire up ardour and JACK is running, too. That's fine!
But: Ardour won't play sound through the headphone jack, but only using the internal speakers (it's a notebook). This is the case just with this JACK-depending application: Once JACK is stopped, I can listen to music and system sounds via headphones again. Just Ardour plays back only via the internal speakers.
I believe this is more a JACK-related thing, but I didn't find a solution on jackaudio.org, neither
a forum - that's why I'm here.
Any hints? Thanks in advance,
