Hi all,
I'm using the FastTrack network to download files through Apollon everything works fine, but then I wanted to listen a mp3 in Apollen, so I pushed the Player button and it said that I had to install KDE MM packages, I did that and hurray!!

the player could be started....
I WAS happy

because, it started playing the file, but I didn't hear any sound

...
So my problem: how can I make the internal player of Apollon play the music properly?
