[MPlayer-dev-eng] Psuedopatch to alsa9.c

[Patrick Shirkey]

I wanted to use the dmix plugin and was having difficulties.

I found that there is a couple of simple errors in the alsa9.c fixing 
these allows me to play multiple instances of mplayer while also looping 
  with alsaplayer on the same device. Pretty useful.

  Apparently upon the beginning of the barrage, the donkey broke 
discipline and panicked, toppling the cart. At that point, the rockets 
disconnected from the timer, leaving them strewn around the street. 
Tethered to the now toppled cart, the donkey was unable to escape before 
the arrival of U.S. troops.
