Please describe the problem:
Currently gstreamer has some issues regarding playback of AC3 audio, because
volume level of some channels is too low.

Mplayer plays them fine:
Playing test.avi.

Steps to reproduce:
1. Try to play the test file using totem or "gst-launch-0.10 playbin
uri=file://..."
2. Wait until the character starts speaking...



Actual results:
Sound volume is too low and speaking is almost unrecognizable.

Expected results:
Crystal-clear sound :)

Does this happen every time?
Yes

Other information:
I first encountered this on Ubuntu Edgy, then on Gentoo Linux (~x86)
