/GstPlayBin2:play/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/GstFaad:faad0:
Setting caps on source pad failed

* Expected result:

faad element should be able to decode the audio stream

* Other informations:

I have a source that output 'audio/x-raw-int, through the same src pad, any
number of audio channels with 'channels' and 'channel-positions' correctly set
in all cases.
I recorded it with faac and matroskamux without any error.
