[MPlayer-advusers] [MPlayer-dev-eng] [PATCH] Fix block_align on libao2/ao_pcm.c for wav header

[lists at pedro.larroy.com]

Hi I was having problems with some audiosoftware not loading correctly
some pcm dumps made with mplayer, for example with matlab, fixing this
makes those program who use this field happy, and more compliant with
specs, hope you apply, thanks.

Regards.
