This file is broken. 

qtdemux has 44100 as the samplerate (this is correct) but then calculates
timestamps as if it's a 48000 Hz file. This screws up the timestamping. vlc and
xine also skip badly while trying to keep up with the timestamps. mplayer seems
to ignore timestamps and plays this ok.

There is not much we can do about that because alac does not have a fixed
number of samples in a frame. This means we can't estimate the samplerate and
correct.

We could disable timestamps in playbin2 when dealing with audio-only files but
that seems like the wrong thing to do.
