in reply to Playing wav file to certain sound card/output

If you have the time to look thru some docs, you might want to look at SDL. It is cross-platform, and works quite well. Look at the test directory of the SDL-perl module for a wave example. I think SDL is up-and-coming to be the standard multi-media library. It is cross-platform, works under any window manager, and performs well.

Here is a sample script to play a wave, there must be a place to select which card to use somewhere down in there. 

#!/usr/bin/perl -w
use SDL::Mixer;
use SDL::Music;

$mixer = eval { SDL::Mixer->new(-frequency => 44100, -channels => 2, -
+size => 1024); };

$mixer->music_volume(100);

$music = new SDL::Music './1bb.ogg' or die $!;
#$sound = new SDL::Sound 'z.wav' or die $!; 

$mixer->play_music($music,5); #0 for single play 

while(1){
if( $mixer->playing_music() ){sleep(1)}else{ last}
}
