[MPlayer-users] MPlayer – changing ‘ao=’ codec order in mplayer.conf does not appear to work for per user config?

FIXED - well 'fudged' is a more accurate description.
One could argue and say there is a limitation with MPlayer only looking for
an environment value 'HOME' rather than a more robust mechanism to
determine a users 'home' directory....

Running MPlayer with 'env HOME=/var/www' will help MPlayer locate the users
config file without having to edit /etc/mplayer/mplayer.conf. This also
fixes the need to run MPlayer with sudo:

playing_mplayer=subprocess.Popen(['env', 'HOME=/var/www', 'mplayer',
'-slave', '-nocache', '-quiet', '-volume', '60', '-key-fifo-size', '2',
'-input', fifoFile, '-playlist', '
http://tx.whatson.com/icecast.php?i=magic1054.mp3.m3u' ],
stdout=subprocess.PIPE, stdin=subprocess.PIPE, stderr=subprocess.STDOUT)

The output run from a browser and 'slave' commands sent to fifo by user pi
on command line in terminal (using config in /var/www/.mplayer with alsa
first in list and the default /etc/mplayer/mplayer.conf) :
