[Libcdio-help] cdda-player: no sound/music

[Ralf Eichinger]

I installed libcdio-utils 0.81-4 under Ubuntu 10.10.
I wanted to play a music cd by calling cdda-player.
It starts, the seconds are counted up, but no sound to hear.
alsamixer shows volume set to full.
xine plays it without problems, user is in group audio and cdrom.
...
What is the problem?
Has it problems with alsa?

Please help, because I want to use the library for programming an own
little cd-player...
