no sound with Audacity

[Uwe Geercken]

hello together,

I prepared a lesson at home today, to get the kids familiar with  
audacity, which I had promised them already a while ago.

unfortunately when I came into the classroom I had to find out, that  
there is no sound when I click on play on the thin clients. I tried to  
change the output device from the audacity preferences dialog (several  
ALSA choises displayed: digital, analog, surround, ..), but without  
luck. but I can play the mp3's with Totem.

Btw.: I also have no sound on the server using audacity.

I guess I am missing a library on codec or so. can somebody help, please.

rgds,

uwe
