i tried this: gst-launch-0.10 -v filesrc location=hartz_IV.mp3 ! mad ! audioconvert ! alsasink device=hw:1 which results in the following error output: ---[snip]--- Setting pipeline to PAUSED ... Pipeline is PREROLLING ... /pipeline0/mad0.src: caps = audio/x-raw-int, endianness=(int)1234, signed=(boolean)true, width=(int)32, depth=(int)32, rate=(int)44100, channels=(int)2 ERROR: from element /pipeline0/filesrc0: Internal data flow error.
