Comment 10 for bug 1096658

So, the problem is reproducible outside SoundConverter already. With the GStreamer pipeline that doesn't manage to convert the file either.

What audio player do you play your APE files with?

The following is a simple GStreamer pipeline to play it via ALSA and/or Pulse Audio (alternativel "pulsesink" instead of "alsasink"), which should work except for maybe minor buffering issues:

gst-launch giosrc location="file:///home/tim/test.ape" name=src ! decodebin name=decoder ! audioconvert ! audioresample ! alsasink
