[Ardour-Users] No sound from my speakers

[German]

Hello list. First of all I have to say that I am complete newbie to Ardour. I just installed it
two hours ago. What I was trying to accomplish was to record some audio from my usb digital piano.
Track seemed to record ok, but when I hip "play" no sound out of my speakers. And it seems that all of my audio
on this system ( Linux 64 bit) are screewed. My music player won't work. Thanks for any clues
