[gst-devel] Can't make gestreamer work - please help.

[Johannes Graumann]

Hello,

I have a Debian testing Via based home server and have just set up Alsa.
Now I'm trying to use gstreamer to play music from command line - xmms
works, as does mpg123.

So I issue this command:
gst-launch filesrc location=file.mp3 ! mad ! alsasink

The result of this is:
INFO (11355: 0) Initializing GStreamer Core Library version 0.6.4 
INFO (11355: 0) CPU features: (00000673) MMX 3DNOW

Google didn't help. Can anybody point me at where to look to solve this.

I'm an obvious newby and at the end of my capabilities ...
