Before using any kind of a sound server, I successfully ran an .asoundrc
that copied the left-front and right-front channels to the right-rear,
left-rear, center, and lfe channels. This way I could play stereo
sources to all of my 5.1 speaker system (I was always successful getting
a stereo stream to play right-front/left-front.) Since installing
pulseaudio, I have not been able to figure out the syntax within
default.pa to create this same setup. I have successfully gotten
mplayer to play 5.1 sound (commercial DVD) correctly, and currently
stereo source does play right-front/left-front. I want to tackle this
stereo issue, then I will move on to flash.
Is it possible to do this? If so could someone help me with the
appropriate syntax?
As a side note: gmplayer works fine using the below. smplayer does not.
It appears that smplayer does not read mplayer.conf and specifically the
"ao=" directive (which I have set to "ao=pulse". It assumes and starts
mplayer with the directive "ao=alsa". Even if you pass the directive
through smplayer's preferences "mplayer -ao 'pulse' " it appears to
overwrite this later in it's startup command with "ao=alsa".
