e2049edb4e Add forgotten line to silence a warning for int32.

same channel ordering for FFmpeg and alsa.

1e96d4c71e ALSA: fix a stupid bad use of av_freep. 
It caused a segfault when channel reordering was in use and the last chunk
of data was not silent.
Spotted and diagnosed by Carl Eugen Hoyos.

813dbb4442 ALSA: implement channel layout for playback. 
Currently, only S16 quad, 5.1 and 7.1 are implemented.
Implementing support for other formats/layouts and capture should be
straightforward.

7.1 support by Carl Eugen Hoyos.

ba87f0801d Remove explicit filename from Doxygen @file commands. 
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

419bddd366 Include alsa headers before the internal FFmpeg headers. 
This avoids symbol redefinitions problems, for example avoids the "free"
symbol to be redefined before system headers actually using it are
included, thus breaking compilation. In particular this change allows
to build FFmpeg with salsa.

bad5537e2c Use full internal pathname in doxygen @file directives. 
Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.
