+ NAME
+ hpplay
+ PURPOSE
+ Play .au sound files on hp9000s700
+ BUGS
+ I have been unable to figure out how to use the volume feature, so no
+ attempt has been made to honor the volume arg of play_sound_*
+ This means that all sounds are played at 100%.
+ The gain parameter can be set by using the hp-play-gain variable.
+
+ NOTES
+ This file is mostly based on the player program found in the examples
+ directory of the audio software delivered on our machines. The path I
+ found it under was /usr/audio/examples/player.c
+ This file contained no credits and no copyrights. The original fileheader
+ is given below.
