The file from ticket #4747 does not contain an alac atom which is required for alac decoding. Instead it contains the necessary data in the wave atom (where you normally would find the alac atom). To distinguish, it would be necessary to look "into" the wave atom to know if it contains an alac atom or not. I meanwhile found that the mpeg demuxer sometimes seeks eight bytes back which I will probably copy. The alternative, iiuc, would be to copy the whole wave atom into a buffer and call mov_read_default() from the wave_read() function with that buffer. But this should not be necessary if somebody can confirm that it is ok to seek back x bytes in a demuxer. As an alternative the current version could also be committed, I am not sure.
